Late by about 40 minutes after being stuck in traffic, Johnny Depp made a rare public appearance at the Cannes press conference for `Jeanne du Barry`, a costume drama that opened the 76th edition of the film festival, reports `Variety`.

The movie marks the actor`s first leading role in three years, following his high-profile legal battles with ex-wife Amber Heard. As he re-emerged into the limelight, Depp appeared to have mixed feelings about his absence from Hollywood films, `Variety` adds.
