Lindsay Lohan and Charlie Sheen have joined the cast of Scary Movie 5 for Dimension Films and director Malcolm D. Lee. We reported last month that Lindsay Lohan was in talks to join the sequel, although now her deal is finalized.

It isn't known what character the actress will play. It is believed that Charlie Sheen will reprise his role as Tom Logan from Scary Movie 3 and Scary Movie 4, despite being killed off in the last movie. Ashley Tisdale has already signed on to star.
