Lindsay Lohan hasn't had a good year so far ... maybe this upcoming role will turn her luck!
Lindsay is going to join the cast of a crazy movie; she's going to be a Manson girl in the movie Manson Girls.
Lilo will play Nancy Pitman, once a loyal member of Charles Manson's freaky band.
Before starting shooting Manson Girls Lohan will shoot the comedy Ye Olde Times with Jack Black and David Arquette this spring.

If you're not familiar with Charles Manson ... he's one twisted dude!
Manson is a convict who led the "Manson Family" that arose in California in the late 1960's. He was found guilty of conspiracy to commit the Tate-LaBianca murders, which members of the group carried out at his instruction. He was later convicted of the murders themselves.
Before strting the Family, Manson was an unemployed ex-convict, who had spent half his life in correctional institutions for a variety of offenses!
He's in prison now, was set for the Death penalty, until it became illegal in California, so it's been lowered to life in prison! He won't be eligible for parole until 2012. Thank God!

As for Nancy Pitman herself ... (after the jump)

Pitman grew up in wealthy household in Malibu, and at 16 she was introduced to Manson by a friend, according to published reports. She fell under his spell, moving in with him and becoming one of his most ardent followers. She was home with Manson on the night he dispatched members of his "Family" to the former home of ex-business associate Terry Melcher, where they ended up brutally killing actress Sharon Tate and four others.

Pitman, aka Brenda McCann, later became involved with the Aryan Brotherhood and served 18 months in prison after being convicted of being an accessory after the fact to murder. She later married one of her co-conspirators, divorced and moved to Oregon with her two children.
