Sporting a black suit at the event, Depp, 51, was all smiles when posing on the red carpet with Heard, 28, who also sported a black suit and matching loose pants at the January 19 event, reported BBC.
Depp's co-stars Paul Bettany and Carly Steel were also present, but the movie's lead actress Gwyneth Paltrow who plays the titular character's wife was missing.
Bettany looked dapper in a dark long overcoat, a white shirt and a grey tie. Steel, meanwhile, looked gorgeous in a grey, patterned dress.
