Captain America and Iron Man put differences aside to make dying fan's dream come true

Avengers co-stars Robert Downey Jr and Chris Evans became real life superheroes recently when they joined forces to make a dying fans dream come true.

After Captain America Civil War it seemed like it would take a miracle for Cap and Iron Man to put their differences aside and work together, and that's just what happened - with a little help from Pepper Potts.

Downey Jr and Evans were joined by their fellow Marvel actress Gwyneth Paltrow when earlier this month she learned of a fan's illness.
