After becoming a Saturday Night Live cast member, Sandler went on to star in many Hollywood feature films that combined have grossed over $2 billion at the box office.

His film roles include Billy Madison (1995), the sports comedies Happy Gilmore (1996) and The Waterboy (1998), the romantic comedy The Wedding Singer (1998), Big Daddy (1999), Mr. Deeds (2002), Grown Ups (2010), Grown Ups 2 (2013) and voicing Dracula in the Hotel Transylvania franchise (2012-2018).

Some of his films, such as the widely panned Jack and Jill, have been heavily criticized, culminating in a shared second place in the number of Raspberry Awards (3) and Raspberry Award nominations (11), in both cases second only to Sylvester Stallone.

He has ventured into more dramatic territory with his roles in Punch-Drunk Love (2002), Spanglish (2004), Reign Over Me (2007), Funny People (2009), and The Meyerowitz Stories (New and Selected) (2017), all of which earned him critical praise.

Sandler formed his film production company, Happy Madison Productions, in 1999, first producing fellow SNL alumnus Rob Schneider's film Deuce Bigalow: Male Gigolo. The company has produced most of Sandler's subsequent films to date. The majority of the company's films have received negative reviews from critics, with three considered to be among the worst ever made, yet most have performed well at box office.

Others who frequently appear in Sandler films include David Spade, Kevin James, Steve Buscemi, Chris Rock, John Turturro, Peter Dante, Allen Covert, Jonathan Loughran, and Jon Lovitz.

In 2014, Netflix announced a four-movie deal with Adam Sandler and Happy Madison Productions.
