Avengers Infinity War shock: This DEAD hero is BACK – star spotted on Avengers 4 set?

Avengers Infinity War hasn’t even released the new trailer yet and fans are already looking to Avengers 4.

The second part of the Infinity Gauntlet saga is currently filming in Atlanta and reports and photographs from the set have sent fans into a frenzy.

There have already been surprising images of Iron Man, Thor and Hulk that seem to confirm a major theory.

Now a much-missed character who was shockingly killed off in a previosu movie has also been spotted on set.

WARNING POTENTIAL SPOILERS

Spanish fan site Marvel Spoiler Oficial is announcing sightings of Quicksilver.

The report said: “More witnesses from the filming in Atlana report that they saw Aaron Taylor-Johnson on the Avengers 4 set.”

The brother of Scarlet Witch was unexpectedly killed in Age of Ultron so how can he possibly be back?

Although the site stresses that this is “just a rumour” it certainly ties in with the increasingly likely idea that Avengers 4 will feature a major alternate timeline plot.

Similar reports also place Crossbones star Frank Grillo in Atlanta with the cast. The mercenary was killed in Captain America Cvil War.

Shots of Chris Hemswoth as Thor have shown him sporting long hair which means the new scenes being filmed must take place before the events of Thor Ragarok when his famous locks are cropped off.

Fans have been quick to suggest that Doctor Strange could use the Time Stone so that the heroes can travel back and change history.

Others think Thanos will fracture the very nature of Time and Space when he reassembles the Infinity Gauntlet.

A more simple idea for Quicksilvers return was suggested which would see Thanos create an illusion of the fallen hero to deceive and defeat Scarlet Witch.
