Iron Man’s Don Cheadle to show his metal in Sun webchat

 IRON Man 3 is set to soar to box office glory this Spring.

And we have our own live superhero webchat with actor Don Cheadle – AKA War Machine — at 3.05pm today.

Following the huge success of the last two instalments – and the record breaking Marvel movie Avengers Assemble – the movie is guaranteed to be a big hit.

Robert Downey Jr returns as Tony Stark, whose alter ego goes into battle against international terrorist The Mandarin, played by Sir Ben Kingsley.

Helping him out, for the second time in a row, is James Rhodes, who boasts his own armoured suit as War Machine.

 This time, with Stark missing, presumed dead, his iron-clad sidekick is in the frontline of the war against terror, called in by the US government to track down the elusive aggressor.

Tune in later to catch Don in the Sun hotseat, ready to answer your Marvel-ous questions.

Don has starred in numerous hit movies including Ocean’s Eleven and Twelve, Boogie Nights and Crash.

In 2005, his performance in Hotel Rwanda landed him nominations for an Oscar and a Golden Globe.

And earlier this year he scooped his second Globe for his role in the TV series House of Lies.

Away from the screen, Don is a talented musician who plays saxophone, writes music and sings.

If you have any questions for Don, leave them below – or come back at 3.05pm today to put them to him live.

Iron Man 3, which also stars Gwyneth Paltrow and Guy Pearce, is released on May 3.
