The Avengers star teamed up with bosses at social media platform escapex to create the free Jeremy Renner app, which allows him to communicate with his fans directly. The mobile app also features exclusive content and news.

Renner has also launched a contest, in which a lucky fan will be flown out to Comic Con Calgary to meet the 46-year-old next month (Apr17).

"I'm always looking for new ways to connect directly with my fans all over the world in our own shared environment," the actor says. "The escapex platform makes it possible for me to deliver exclusive content and the latest news to my fans all from my mobile phone at any time of day.

"So download my app, become a superfan and tell me in the comments why you want to join me at Comic Con Calgary. I can't wait to see you there!"

Renner is not the only celebrity to get into the mobile app business - Tom Hanks, Zendaya, and Dwayne Johnson have also launched their own platforms.
