Breakup at a Wedding (2013) on Netflix

Plot summary

Wedding videographer Vic James has ten years in the business and free run of the nuptials of Alison Jones and Phil Havemeyer, since Alison lets him film whatever he likes and Phil is distracted by his iPhone. At the rehearsal dinner the night before, Alison gets cold feet, blaming her parents' failed marriage, and thinks she and Phil will break up eventually. She talks him into holding the ceremony without signing the marriage certificate, so nobody else has to know. Phil agrees, hoping a surprise gift will win her back, and has asked his boss, Damian Haines, to be his best man without telling his oldest friend, Chris "Bena" Benaschnaz. Alison's maid of honor, Mary Kowalchik, has her own plans.
