At the 2015 Golden Globe Awards, Kevin Hart went on record saying this film was his best work to date and is most representative of his work on-stage as a stand-up comedian.
On January 21st, 2015, Kevin Hart bought out two shows of The Wedding Ringer in a theater near Toledo, Ohio. He then urged his fans to "tell them Kevin Hart sent me." 500 patrons were then treated to a free showing of The Wedding Ringer.
Early in the film when Doug (Josh Gad) falls through the desk he yells out, "I can't feel my **** legs!" In Frozen (2013), Olaf (also voiced by Gad) yells, "My legs! I can't feel my legs!".
In the old timers versus groomsmen football scene, three of the old timers are true legends of football, playing in the positions they did in their professional football careers:
- Joe Namath, quarterback for the New York Jets from 1965 to 1976, he who is wearing his signature #12.
- John Riggins, fullback with the New York Jets from 1971 to 1975, and with the Washington Redskins from 1975 to 1979, then again from 1981 to 1985.
- Ed 'Too Tall' Jones, defensive end for the Dallas Cowboys from 1974 to 1978, then again from 1980 to 1989.
