From NetFlix:

Food writer Julianne Potter (Julia Roberts) panics when she gets word that her longtime platonic pal, Michael (Dermot Mulroney), is finally getting hitched, to a debutante named Kimberly (Cameron Diaz). With assistance from her gay companion (Rupert Everett) — and to the accompaniment of Burt Bacharach tunes — she sets out to sabotage the wedding and make a last-minute play for her man. James Newton Howard’s score received an Oscar nomination.

Julia Robert’s classic effort to sabotage her friend’s wedding. Did you
ever see an entire restaurant break out into song ? Definitely a feel-good.
