Iron Man 3 best superhero movie ever: Downey Jr

London: Actor Robert Downey Jr thinks 'Iron Man 3' could be the best superhero movie ever made.

The 46-year-old is looking forward to working with director Shane Black on the third movie in the franchise and is confident it will not only be better than the previous offerings in the series, but could top anything ever made in the genre.

"I think that we have an opportunity with the third 'Iron Man' to make the best of the three, and maybe one of the better superhero movies that's ever been made," femalefirst.co.uk quoted Downey Jr. as saying.
