Mark Waters is in negotiations to direct "Will Sebastian" for Warner Bros. Pictures. Chris Columbus, Michael Barnathan and Mark Radcliffe are producing through their 1492 Pictures. Written by David Hubbard and described as having elements of "Big" and "Forrest Gump," "Sebastian" tells the story of a guy who lives his life out of sequence and the woman with whom he's destined to fall in love. Courtenay Valenti is overseeing the project for the studio. Waters directed Walt Disney Studios' summer sleeper hit "Freaky Friday," which grossed more than $110 million. He is completing Paramount Pictures' "Mean Girls," which stars Lindsay Lohan and opens April 30. He also directed the critically acclaimed "The House of Yes." Waters is repped by CAA.
