London: Actors Robert Downey Jr, Chris Evans and Gwyneth Paltrow paid a surprise visit to Ryan Wilcox, an "Avengers" fan who is battling cancer.

Ryan Wilcox, 18, is a huge Marvel fan and especially loves Chris Evans' Captain America so Gwyneth Paltrow, who played Pepper Potts in 'Iron Man', arranged for him and Robert to fly to San Diego, California, to visit him, reported Female First.

She shared a picture of the two actors with Ryan and wrote, "Today @ryanwilcox0303 got a little surprise. Thank you to the incredible #chrisevans and my better work half @robertdowneyjr for being the men you both are. And thank you to the Wilcox family for your hospitality! #ryanstrong (sic)."
