"I have so much faith in [Siverston], just as a person, and I just love working with him," Lohan told EW. "I love him [so much] as a person, that while we were on set, I was like, 'Let's make a deal right now.'"
The plot of the film hasn't been officially released, but Lohan describes it to Entertainment Weekly as being about a group of kids taking a cross-country trip when one of them drops acid, goes crazy, ''and starts, like, killing people.''
Marc Senter has been cast in Hippy, which if Lohan lands a role in the film, would reunite the duo, as they both appeared in Siverston's 2005 horror drama, The Lost.
No word on when Hippy will start production.
