Another Marvel star has hinted they’re in Avengers: Doomsday, and it could set up a heartbreaking Tony Stark moment

Gwyneth Paltrow has hinted that she recently worked on a secretive film where she was unsure which character she was playing, prompting Zoe Saldaña to say “Pepper”. Fans believe the exchange may suggest Paltrow is returning as Pepper Potts in *Avengers: Doomsday*, though neither actor named the film.

A possible return could connect Pepper to Robert Downey Jr’s casting as Doctor Doom, raising speculation that the story may link the villain to Tony Stark, perhaps through a variant. The film is due in UK cinemas on 16 December and in the US on 18 December; Paltrow’s comments have not confirmed her involvement.
