FINALLY! We've been waiting for the moment Brad Pitt would return to the spotlight after his difficult divorce from Angelina Jolie and all the dramatic accusations lodged against him in the bitter battle ... and finally, he's back!

Pitt was in high spirits at the Cannes Film Festival photo call for his new film Once Upon A Time co-staring the equally as exciting Leonardo DiCaprio and the beautiful Margot Robbie ... and directed by Quentin Tarantino -- what more could you ask for in a film! Here's the synopsis from Sony Pictures: "Once Upon A Time visits 1969 Los Angeles, where everything is changing, as TV star Rick Dalton (Leonardo DiCaprio) and his longtime stunt double Cliff Booth (Brad Pitt) make their way around an industry they hardly recognize anymore." Check out the trailer for the movie which opens July 26 (we've got to wait a while!) ...
