Demi Moore has been increasingly despondent and saddened about the path of her acting career has taken in the past 18 months and has increasingly grown dependent on prescription medication to deal with her anxiety and depression, RadarOnline.com is exclusively reporting.

As RadarOnline.com previously reported, the 49-year-old actress has been struggling with anorexia and taking the prescription pills Adderall leading up to her seizure on January 23.

The Striptease star "is very, very unhappy with her acting career. Demi is despondent because she feels that her career has stalled. It's been a very long time since Demi was the marquee star that would open a movie. One of the reasons that Demi is obsessed with being young is that she feels if she is seen out with her daughter and Rumer's friends that might help increase her chances of being offered a role that might go to a younger actress," a source close to the actress tells us.

Demi Moore 911 Call: ‘She’s Convulsing’ And ‘She Smoked Something’

Getting the story of Lovelace, who died 10 years ago, to the screen has not been easy. Lindsay Lohan was at one time tied to another project about the infamous porn star.

Demi Moore was rushed to the hospital Monday night after a 911 caller from her home reported that she'd gone into "convulsions" after she "smoked something."

That something, RadarOnline.com reported, is believed to be a synthetic drug called K2 Spice.

Moore has since been released from the hospital and has reportedly entered rehab.

Inferno director Matthew Wilder has told RadarOnline.com: "We would never have got our movie made if Lindsay Lohan was still attached to it."

Wilder went through a rollercoaster of emotions when the troubled actress was supposed to be playing tragic porn star Linda Lovelace as her never ending legal woes constantly threatened to torpedo the project.

And now that she is facing the possibility of up to three years in state jail if she is charged with felony grand theft plus six months for breaking her current probation, Wilder has been left scratching his head.

"To tell you the truth I have a total sense of relief because the reality is we would never have got our movie made if Lindsay Lohan was still attached to it." He told RadarOnline.com.

"We are now due to start filming in New Orleans in April with Malin Akerman instead of Lindsay Lohan and everybody cannot wait.

"Despite everything that happened with Lindsay I would be horrified if she went to jail and to tell you the truth I just feel sorry for her because sadly she has some real issues to deal with.

"It was funny because the paparazzi followed Malin recently but it was a completely different vibe to Lindsay because she is such a different person.

"I can now just look forward to making our movie without any distractions and that just couldn't happen when we were involved with Lindsay Lohan.

"I'm not sure if I was surprised or not that she got into trouble again I just wish she could get her life together at some point despite everything she put me through."

RadarOnline.com revealed that Lohan will not be charged today with felony grand theft in connection with the $2500 necklace she allegedly stole from a boutique in Venice.

The former Mean Girls star is facing a legal nightmare as there is CCTV footage of her wearing it out of the store.

In addition she could still be charged in Riverside in connection with her alleged assault of Betty Ford care worker Dawn Holland last year although RadarOnline.com understands that this would only be a misdemeanor and that Beverly Hills Judge Elden Fox is not likely to take action against her over this particular incident.

The Doomsday scenario for the actress is she's facing felony grand theft charges, which could lead to her probation from her prior DUI case being automatically revoked by Judge Fox resulting in serious jail time.

The theft charges are expected to be filed this week - more disturbing for her friends and family, as RadarOnline.com exclusively reported Lohan lied about ever being inside Kamofie & Company in Venice and she now  could be about to pay the ultimate price for her deception.

Though he continues to root for Lindsay Lohan’s recovery and success, Inferno director Matthew Wilder admits that his decision to recast her starring role has given him some peace of mind. In an exclusive interview with RadarOnline.com, Wilder discusses his choice and his new leading lady.

Wilder recently brought in actress Malin Akerman to replace Lohan in the movie based on the tragic porn star Linda Lovelace. “I love working with her, she is sensitive and hard-working and I think it’s a great decision for our project,” he said about Akerman.

With Lohan, the production had to endure many costly delays due to the actress’ ongoing personal and legal struggles, including her ongoing rehabilitation treatment at The Betty Ford Center.

Director Matthew Wilder has wasted no time in replacing Lindsay Lohan as the star of his upcoming Inferno, RadarOnline.com has learned.

He's brought in superhot Malin Akerman to star in the Linda Lovelace biopic, Deadline Hollywood is reporting.

Malin, who shot to fame in the Vince Vaughn comedy Couples Retreat, is now costarring with Jennifer Aniston and Paul Rudd in Wanderlust, shooting in New York.

RadarOnline.com was the first to reveal that Wilder was backing away from his long support of the troubled Lohan to star in his movie. On Wednesday he told us he had a "Plan B" in place.  And yesterday, Wilder told us it was a done deal.  "We've fired Lindsay," he said, revealing that "we've already lined up somebody else who we are really happy with."

Lindsay's camp is insisting she wasn't fired, it was her decision to pull out of the film.

Either way, Akerman is a great "get" for Wilder and moves the project up several notches.  There's no word yet on when they'll start shooting.

Lindsay is set to complete her court-ordered treatment at the Betty Ford Center on January 3.

"We have fired Lindsay Lohan from Inferno and we have already lined somebody else up, who we are really happy with, to play the part," Matthew Wilder tells RadarOnline.com exclusively.

"I don't want to say too much just now or anything that I may regret, but I believe it is best for all parties concerned that we do Inferno without Lindsay."

Wilder and his producers ran out of patience with Lohan when she didn't meet with them while she was at her West Hollywood apartment on a day pass from the Betty Ford Center last weekend, several sources tell RadarOnline.com.

Lindsay is under court-ordered treatment at Betty Ford until January 3.  Ironically her father Michael was always opposed to Lindsay starring in the Linda Lovelace biopic.

But now Wilder tells RadarOnline.com that he is developing a 'Plan B' if Lindsay can't shoot the movie.

After less than a four-week shut-down brought on by the discovery that an actor had tested HIV-positive, porn industry cameras are rolling again, RadarOnline.com has learned.

Two of the biggest companies began shooting again last week and Vivid Entertainment announced it will resume on Monday. All the companies involved have their studios in LA's San Fernando Valley and it is not uncommon for porn stars to work for multiple producers.

The shut down began October 12 after an actor, referred to as Patient Zeta, tested positive for HIV. The situation was called a "time bomb" by former porn superstar Jenna Jameson in an exclusive interview with RadarOnline.com.

"We can now confirm that all performers who were on the quarantine list as a result of being exposed to the HIV positive performer have gone through two rounds of testing and the results are negative," said Vivid co-chairman Steven Hirsch.

But guidelines from the AIDS Healthcare Foundation indicate the porn studios should wait at least another month before putting exposed performers back on the job. "It could be anywhere from 12 weeks to six months that an HIV infection could appear," explained communications director Ged Kenslea.

Lindsay Lohan has presumably turned down the porn role she was offered even though it would have helped may her bill at the Betty Ford Center. She is still scheduled to star as the late porn star Linda Lovelace in a biopic titled Inferno.
