Robert Downey Jr is offering fans the opportunity to be his date at the world premiere of Avengers: Age Of Ultron in Los Angeles.

The actor, who reprises his role as Tony Stark/Iron Man in Marvel’s superhero sequel, is taking part in the special event to raise funds for Dorset-based children’s hospice, Julia’s House.

The once-in-a-lifetime experience includes breakfast at Randy’s Donuts before enjoying an action-packed day including a helicopter ride over the Hollywood sign and indoor skydiving as well as a custom gown or tux fitting before meeting the actor himself for a caviar tasting.

The winner will then join Robert in his private motorcade as he heads to the film premiere on April 13, where they could also meet his co-stars including Chris Hemsworth, Mark Ruffalo, Scarlett Johansson, Samuel L Jackson, Chris Evans and Jeremy Renner.

The competition, which also includes flights to Los Angeles, 4-star hotel accommodation and all transport, is open until April 6.
