Netflix says it's set in '90s Los Angeles, but aside from that, details are scarce. Same goes for anything regarding the other three movies. But, maybe that lack of information is a good thing. Who knows, Sandler could surprise the cynics with another Punch-Drunk Love, Reign Over Me or Funny People. Stranger things have happened -- especially on Netflix.

Update: If you're looking for more information on Sandy Wexler, the IMDB page is a good source, or you could just check out the trailer below.
