In the original Death at a Funeral (2007) screenplay, the character that Peter Dinklage ended up playing (named Peter) was of average height, and not written as an achondroplastic dwarf. The character was changed for him after he auditioned and was cast. He then became the only actor to reprise his role (with the name of Frank) in this remake.
In one scene, Ryan (Martin Lawrence) clarifies that Aaron (Chris Rock) is only a few months older, both were born in the same year. In real-life, Chris Rock and Martin Lawrence were born 1965, but Chris Rock is older.
This movie is a remake of the 2007 movie of the same name. Although Hollywood has a history of making American versions of foreign films, the original versions are usually in a language other than English. Not the case here, since the original film was a British production and filmed in English. This is a very unusual case of a remake being made very quickly of an English-language movie that had a theatrical release in the U.S. Both versions of the story enjoyed success worldwide. The 2007 version earned just over forty-six million dollars, and this version earned just over forty-nine million dollars.
Three members of the cast have appeared in movies based on Marvel comics: James Marsden in the X-Men film franchise; Zoe Saldana as Gamora in the Marvel Cinematic Universe, and Peter Dinklage as Bolivar Trask in X-Men: Days of Future Past (2014) and Eiltr in Avengers: Infinity War (2018).
This film features Ron Glass, who starred on Firefly (2002). Death at a Funeral (2007) featured Alan Tudyk, who also starred in Firefly (2002). Glass and Tudyk appeared in the "Firefly" follow-up movie, Serenity (2005).
One of the oft-mentioned photographs involving Edward (Bob Minor) and Frank (Peter Dinklage), features them dressed as Deena and Effie attending the premiere for Dreamgirls (2006).

Danny Glover, who plays Uncle Russell, co-starred in the film version as Marty Madison.
