The failure of Jack and Jill hasn't deterred Adam Sandler from producing movies. He'll now ramake 80s comedy, Summer School.
According to Collider, Sandler's production company, Happy Madison, have teamed with Paramount Pictures to produce the film about a lazy gym teacher, forced to teach summer school to a bunch of degenerates. NCIS star Mark Harmon was the slacker lead, and the flick was directed by legendary comedy helmer, Carl Reiner. I don't remember too much about the film but you can have a looksie at the trailer below.
Sandler will apparently not star in the movie, but it would be a good role for him looking at said trailer.
