Lindsay Lohan 'The Canyons' Trailer Debuts As Director Says 'Lohan Has More Natural Acting Talent Than Monroe' (VIDEO)

Lindsay Lohan's latest director, Paul Schrader, has confirmed what many have suspected for a long time - the 'Mean Girls' star is difficult to work with.

However, he's also stuck up for the troubled actress, insisting the on-set battles were well worth it and likening her to Marilyn Monroe.

Lohan, who is currently in rehab under a judge's orders, plays an aspiring actress drawn into the world of porn in 'The Canyons', written by controversial author Bret Easton Ellis.

The trailer has just debuted online (above) and is filled with erotic shots of a nearly-naked Lindsay.

Schrader, famous for writing 'Taxi Driver' and directing 'American Gigolo', has written an essay for filmcomment.com in which he compares Lindsay, 27, to the late Marilyn Monroe.

He said: "Similarities? Tardiness, unpredictability, tantrums, absences, neediness, psychodrama - yes, all that, but something more, that thing that keeps you watching someone on screen, that thing you can't take your eyes off of, that magic, that mystery...

"I think Lohan has more natural acting talent than Monroe did, but, like Monroe, her weakness is her inability to fake it. She feels she must be experiencing an emotion in order to play it. This leads to all sorts of emotional turmoil, not to mention on-set delays and melodrama.

"LL lives in a world of instant celebrity gratification Monroe could have only dreamed of. Paid for public appearances, paid to wear clothes, paid to pose, paid for gossip tips, paid for tweets. These rewards are available without the pretence of responsibility. On the other hand, there's no system to protect today's celebrities from the media or the courts or themselves.

"From a selfish point of view, from a director's point of view, that is, from my point of view, it was a treat to work with Lindsay. All the drama, the mishegas, all the stress - that means little. A director can shoot around misbehaviour. He can't shoot around lack of charisma. I just wish it was easier for Lindsay."

'The Canyons' debuts in the US on iTunes and cinemas on 2 August. Watch above and let us know if you think it will be better or worse than 'Liz & Dick', Lohan's last noticeable acting gig.
