Promoting a film can be tiring, we're sure.

There's the endless five-minute press junkets answering similar questions in succession, endless red carpet posing at premieres (though we best the dressing up is fun) and the photocalls.

But, during the official photocall for Quentin Tarantino's latest film Once Upon A Time In Hollywood, Brad Pitt decided to inject some fun into the whole process.

Margot Robbie, who plays the late actress Sharon Tate in the film, was working the camera, as always, for her portraits - in a beautiful Derek Lam Jumper and wide leg white trousers - when Pitt photobombed the entire thing.

The actor, wearing a flatcap and casual t-shirt and trousers, performed a series of grand jetés in front of the camera, some facing towards the photographer, others towards Robbie.

The actress clearly enjoyed the interruption as she was seen hysterically laughing and reactively posing with a shock-horror look on her face as Pitt showcased his best ballet moves in front of her.

We mean, the arm placement and height he reaches is really quite commendable.

Robbie and Pitt were joined by the director and their co-star Leonardo DiCaprio for the photocall.

The film, which received a seven minute standing ovation when it premiered at Cannes Film Festival, tells the story of the movie industry in 1969.

The film's plot has largely been kept secret but we know DiCaprio plays a struggling actor and Pitt his stunt double, who both become entangled with the family of Charles Manson - who's cult murdered Sharon Tate when she was eight months pregnant, as well as others, in 1969.
