Paper Man: According to Variety, Sideways star Paul Giamatti is attached to topline Paper Man, a comedy mobilizing for an April start.

The film will mark the directorial debut of scribes Michele and Kieran Mulroney.

Giamatti will play a man struggling to recapture the spark that made him a successful novelist. His marriage also is disintegrating, and neither problem is helped by the presence of an imaginary superhero friend who has been with the writer since childhood. On Cape Cod, he strikes up a platonic relationship with a local high school girl that re-energizes him.
