Captain America: Civil War - 10 Characters Who Could Be Last Minute Additions

5. Thor

Although Thor will be sitting out the war itself based on what we know about the line-ups of Team Cap and Team Iron Man, and the character's retreat home after Avengers: Weekend Of Ultron, there does still exist the chance that he make a return to Midgard once the dust has settled to ask just what the f*ck happened whilst he was gone. They'll have to address the fact that Heimdall definitely will have told about Thor about the beef between his earthbound allies, considering that character's ability to see everything happening in the universe ever. Asgard's most attractive god will definitely want to be given updates on such things, and most likely wouldn't mind taking a day off researching the Infinity Stones to check on his buddies. Similarly, Hemsworth is always knocking about Hollywood-way, so it wouldn't be too hard to give the man a call and ask if he would drop by the set.
