Among the film's ensemble cast are actors Josephine Decker, Randy Gambill, Lawrence Michael Levine, Jennifer Prediger, and Tukel himself.

David DeWitt of The New York Times called the film "a slice of the John Cassavetes, John Sayles and Richard Linklater life" and added "Richard’s Wedding is modest in umpteen ways, and if your cinematic diet craves the substantial, be forewarned.

"[2] Ronnie Scheib of Variety added, "Turkel constantly undermines the feel-good with the ridiculous and vice versa, vacillating between infantile insults and professions of affection, a duality that ultimately wears thin.

Still, if the message sometimes veers uncomfortably toward sententiousness, it reaches its comic apogee in Alex’s born-again ex-junkie cousin Louis (Randy Gambill), now an online-ordained minister.

[4] Kenji Fujishima of Slant Magazine gave the film a more mixed 2 out of 4 stars, saying "Richard's Wedding may be admirably nervy in some ways, but in the director's preference for above-it-all contempt over tough-minded empathy, the film ends up seeming little more than an 89-minute hatefest, with no special insights into human nature to make the endeavor worthwhile.
