The Avengers: Age of Ultron trailer is going to be screened at the San Diego Comic Con 2014 if the reports are to be believed.

In a report by the Comic Central City, Marvel Studios are looking to put on a good panel for the fans by showing the much anticipated Avengers: Age of Ultron trailer during the San Diego Comic Con 2014.

The Avengers: Age of Ultron trailer would be vastly different from the teaser shown on the San Diego Comic Con 2013 where no footage from the movie was shown (because filming hasn't started then) but the Avengers: Age of Ultron trailer for San Diego Comic Con 2014 would actually feature real footage from the movie.

A number of news sites are reporting that the Avengers: Age of Ultron post credits scene would be a set up for the Iron Man 4 movie and the Mark Ruffalo Hulk movie, while this theory has been very popular with the fans, these Avengers: Age of Ultron post credits scene write-ups are just rumors.

The Avengers trailer was shown as the post credits scene of Captain America: The First Avenger as it was the last movie before the Avengers movie but this is not the case for the Marvel Cinematic Universe Phase 2 as the Guardians of the Galaxy post credits scene would not show the Avengers: Age of Ultron trailer but a showcase for Richard Rider aka Nova.

The Latino Review has confirmed that Guardians of the Galaxy post credits scene would feature Richard Rider aka Nova as well as Thanos appearing on the movie voiced by Josh Brolin.

While the Latino Review didn't say who was portraying Nova in the Guardians of the Galaxy post credits scene a number of news sites have confirmed that Nathan Fillion is Nova in the Guardians of the Galaxy post credits scene.

With Nathan Fillion as Nova in the Guardians of the Galaxy, does this mean that he won't be playing Green Lantern in the Justice League movie and the Flash/Green Lantern Team Up movie?

Nathan Fillion has been rumored to play Green Lantern for the Justice League movie for a while now and with him being Nova in the Guardians of the Galaxy may put a damper on that rumor as it would not be wise for DC to hire an actor from their competitor, the last time they did that was with Ryan Reynolds for Green Lantern and their venture was not very successful.

With the Guardians of the Galaxy post credits scene confirming Nathan Fillion as Nova, who do you think would play Green Lantern in the Justice League movie and the Flash/ Green Lantern team up movie? Sound off in the comments below!
