Jon Favreau will be in new Spider-Man
Robert Downey jr has already been confirmed to appear as Tony Stark/Iron Man in the picture, which makes sense given his relationship with Spidey in Captain America Civil War. And it seems more characters are coming on board too.
Jon Favreau will have a part in the film as Happy, Stark's bodyguard and friend- though why Iron Man needs protection is beyond us. The character has been in the franchise since the very first MCU movie back in 2008, and Favreau is deeply integrated into this world as the director of the first two Iron Man movies.
