Robert Downey Jr continues his highly expert and entertaining turn as Tony Stark/Iron Man in this reliable sequel.

It takes a while to crank up, but the mayhem at the Grand Prix in Monaco is thrilling and the superhero action hots up to an awesomely exciting climax.

Director Jon Favreau keeps the focus on the actors and the characters rather than merely the CGI and that pays off. Mickey Rourke enjoys himself as the Russian scientist villain – he’s ideal and could do with more dialogue – and Sam Rockwell’s good, too, as the American baddie in league with Rourke.

Also making their mark are Gwyneth Paltrow and Scarlett Johansson, but it’s Downey Jr’s polished performance that forms the heart of soul of the movie.

Though you might ask for a bit more of an actual story, the movie’s as slick and smooth as they come.
