Jon Favreau teases 'Avengers 4' appearance with Paltrow

Actor-filmmaker Jon Favreau and Gwyneth Paltrow are the latest to join the epic superhero team-up "Avengers 4".

The "Iron Man" director reunited with his stars Paltrow and Robert Downey Jr on what seems to be the set of "Avengers 4", with all three looking to be in costume.

"Infinity Trinity #infinitywar," Favreau captioned the photo, which was also shared by Downey.

This would be the first "Avengers" appearance for both Favreau and Paltrow. Favreau, who serves as an executive producer on the franchise, portrays Happy Hogan, bodyguard to Tony Stark/Iron Man (Downey), while Paltrow plays Pepper Potts, Stark's love interest.
