Mary Elizabeth Winstead is the latest promising actor inexplicably signing on to star opposite public trainwreck Charlie Sheen in the semi-autobiographical “A Glimpse Inside the Mind of Charles Swan III”, according to Variety. Also joining the growing ensemble cast are Bill Murray and Patricia Arquette, now rounding out a cast that already includes Jason Schwartzman, Aubrey Plaza and Katheryn Winnick.

Roman Coppola directs Sheen as the title character, a graphic designer whose abundant wealth and charm have made him irresistible to women. When his girlfriend breaks up with him, however, he inevitably begins to downward spiral and eventually go on a hallucination-filled journey of self-reflection and redemption. Ok, sure, but is this just a thinly disguised propaganda film attempting to rehabilitate Sheen’s image? Of course the filmmakers will deny, deny, deny, but if Charlie “Swan” turns out to be an overly sympathetic character, we’ll have our answer. Filming is already underway in Los Angeles.

Winstead recently headlined the remake of “The Thing” to not much success, but remains one of our favorites and has more promising projects on the horizon. She has wrapped playing Mary Todd opposite Benjamin Walker in next summer’s “Abraham Lincoln: Vampire Hunter” and also indie dramedy “Smashed” opposite Aaron Paul.
