As rumors circulate that Li-Lo will receive a cool $1 million for her first post-jail interview the Mean Girls star is preparing to kick-start both her life and career.

Matthew Wilder - who will direct Lohan in her big-screen comeback as tragic porn star Linda Lovelace - has been exchanging e-mails with her while she is being treated in UCLA.

He told RadarOnline.com: “Lindsay is doing really well - she is upbeat and positive. She is looking forward to getting out and getting on with her life and work too.”

Wilder says that they are still casting for the lead role to play opposite Lohan in Inferno and that the actress has been giving him a ‘wish-list’ of actors that she would like and who she has worked with before.

“At the moment we are looking to somebody a little older than her but we appreciate her input and she seems very enthusiastic about Inferno.”

He goes on to say, “We are scheduling to begin filming in November and are confident that Lindsay will be in great shape when the cameras start to roll.”

Lohan will next be seen in theatres in Robert Rodriguez's gory Machete which opens on September 3rd and it looks like she will be released from UCLA very soon.

Her starring role in Inferno - which will involve full-fontal nudity – is seen as a career risk by many movie observers but ironically her profile has never been higher since she was sentenced to 90 days in jail.

The troubled actress was released from Lynwood Correctional Center after serving just 13 days and went straight to UCLA for 90 more days of court ordered rehab.

If the actress serves her full 90 days, it would keep her inside the facility until the beginning of November but according to sources, she will be released much earlier than that.

In recent years, Lohan’s personal life has been plagued with controversy and it may be affecting her movie career as well. She has been missing from the big screen since 2007's psychological stripper flop I Know Who Killed Me and her last hit movie was 2004's Mean Girls.

Matthew Wilder, the director of Lindsay Lohan’s new movie Inferno, told RadarOnline.com that he was banned from seeing the jailed actress and that he still hopes to start production on the film this fall.

Wilder – who is helming the project about the life of porn star Linda Lovelace – was turned away after attempting to visit Lohan at the Lynwood Correctional Facility.

“It was really frustrating because I wanted to see Lindsay in person on Saturday to try and lift her spirits,” he said. “I went down to Lynwood and filled in all the paperwork and waited in line for about 45 minutes only to be told at the last minute that I could not see her because she had used up all her visits. I immediately called her assistant, Eleanor, and she told me that she would in fact not be able to see anybody which was really frustrating.

“I’m told Lindsay’s spirits are good but that it’s difficult for her, as it would be for anybody, to be locked up in a small cell like that.”

Still, he believes that the troubled star will be ready to start filming Inferno this year once she has completed a stint in rehab as part of the punishment handed out by Judge Marsha Revel.

“We had a producers meeting yesterday and if everything goes to plan we are hoping to start shooting Inferno around November 10, 2010, which would be great.

“To tell you the truth I don’t know if all of this publicity about Lindsay will be good or bad for the movie and we are all just itching to get started at this point.

“Hopefully, she can draw from her experiences and when she comes back from rehab she can shows everybody exactly what she can do. Despite everything we still have a lot of confidence in her and back her 100 percent for Inferno.” The young director has gone out on a limb to get Lohan for the role and is hoping that she can pull through for him when the cameras actually start rolling.

In Inferno, there will be some artful full frontal nude shots of Lohan as she tries to portray tragic porn star Lovelace.

Both Courtney Love and Anna Faris had been rumored to play Lovelace before Lohan emerged as the frontrunner.

In recent years, while Lohan’s personal life has been plagued with controversy, her movie career has gone into a tailspin as well.
