“Happy Gilmore,” released in 1996, was Sander and Herlihy’s second movie, following “Billy Madison.” Sandler was just exiting “Saturday Night Live.” Herlihy was Sandler’s roommate at New York University and became a lawyer before Sandler got him to stick to writing comedy. (You might remember the “Herlihy Boy” sketch .)

The sisters are no strangers to Adam Sandler's movies. See the roles they play in "Happy Gilmore 2," plus more to know about the budding stars.
