Good news Marvel fans, new updates for "Avengers: Age of Ultron" have been revealed regarding new trailer, new details of Stan Lee's cameo and a new character appearing in the movie.

The official Facebook of ComicBookResources posted a new trailer of "Avengers: Age of Ultron", and it features a fight scene between Captain America (Chris Evans) and the film's main antagonist Ultron (James Spader).

The near end part of the video shows the first Avenger engaging Ultron in combat on top of a semi-truck as Black Widow (Scarlett Johansson) rides through the streets, and highways trying to give Captain America his shield. As Ultron overpowers Steve Rogers, Black Widow slides below the truck and throws Cap's shield, smacking Ultron right in the face.

Aside from the trailer, Marvel creator Stan Lee revealed new details on his new cameo appearance, FlickeringMyth.com reports.

"My favorite is one I can’t tell you about, but I’ll give you a hint — don’t miss the new Avengers movie,” Lee said.

“Almost every day, I get invited to do a cameo in some movie or another that has nothing to do with Marvel,” he adds. “They just call me up, ‘hey, we’re doing a movie. Do you want to do a cameo?’ It’s kind of funny — I’ve become known as a cameo specialist.”

The FlickeringMyth adds that Lee's character could be another well known Marvel character as fans theorized that he will be the cosmic being Uatu the Watcher.

Another rumored cameo for Lee has been making rounds as Comic Central City reportedly claimed that he is saved by Spider-Man during the "Avengers 2" post-end credits.

"The end credits scene starts with a view of a half destroyed building. Stan Lee is then shown walking around the building as a piece of debris is about to fall on him. As the debris about to hit Stan Lee, Spider-Man swings and grabs Stan Lee, saving him at the last minute. Stan Lee says thanks to Spider-Man as Spider-Man gives him a thumbs up and zips away," Comic Central City wrote.

Lastly, Newsarama has reported that "Before Midnight" star Julie Delpy is rumored to play Amora the Enchantress, and will likely debut in the film.

Screenrant previously reported that Delpy name is included in "Avengers: Age of Ultron" World Premier cast list hinting that Marvel has role in stored for her within the film.

It was reported before that Thor's half-brother Loki will make his presence in post-end credits, not to mention that the Enchantress will also be part of "Thor 3" along with right hand man Scourge the Executioner, and the Fire Lord Surtur.
