Robert Downey Jr says Captain America Civil War is 'like my little Iron Man 4'

Robert Downey Jr's Iron Man is making a big appearance in Marvel's upcoming movie Captain America Civil War, which although is primarily based on Steve Rogers, Tony Stark will be seen an equally important role. Downey Jr has himself called the film as like his "little Iron Man 4".

In an interview with USA Today, the Avengers actor said: "In a way it's Cap 3 but for me it's like my little Iron Man 4 and then it's back to the thing we all recognize. Everything pulls over to the side of the road when the thunder of an Avengers thing comes through because that's how it is until it changes. If it changes..."

Although Tony Stark and Steve Rogers will be on opposing sides in Captain America 3, Downey Jr insisted that his character will not turn into a villain like in the Civil War comics. The 50-year-old actor said, "If we're going to go there, then we've got to save it for my swan song. I would still like to keep a general audience and mildly be in their favor somehow."

Captain America Civil War will be the longest Marvel movie to date. AMC Theaters [via The Playlist] has posted the runtime for Civil War, which shows that the movie will be 2 hours and 27 minutes long, including the credits. The movie opens in theaters on 29 April in the UK and on 6 May in the US. Tickets for the film are already on sale on amctheaters.com.
