No one leaves right when a Marvel movie ends anymore, and the high-grossing superhero epic "The Avengers" continued the trend with its own post-credit scene, which can now be seen online. The few people who missed the blockbuster earlier in the summer can catch up on the short scene leading into the inevitable "Avengers" sequel.

"The Avengers 'A New Threat' Blu-ray/DVD Clip" was posted to YouTube Tuesday. The 49-second scene caused a stir in May when audiences first saw the clip and debated the identity of the mysterious character portrayed there.

As of 3:30 p.m. Tuesday, the few comments the video had collected on YouTube discussed how people in theaters confused the character for Hellboy. "People in the theater I was in? thought it was Hellboy... SMH," wrote user MrCoolStickman.

Movie blog SlashFilm said the character really is the lesser-known villain Thanos, "the Eternal guy with the craggy face who is literally in love with death." The blog went on to say that this clip is "one of the nerdiest moments in all of Marvel's movies," because of the character's obscurity.

Odds are that people interested in seeing this clip have already seen "The Avengers" in theaters. SlashFilm notes that this is geared to the home video release for the film, which is set for Sept. 25, according to Video ETA.

As of Sunday, Box Office Mojo reports, "The Avengers" has grossed $616 million after three months at the box office, making it the third highest grossing film of all time, behind "Avatar" and "Titanic." It should be noted that "Titanic" was originally released in 1997, and had a 3D re-release in 2012 to aid its overall box office gross.

This summer's other successful blockbuster, "The Dark Knight Rises," is competing well against "The Avengers." The finale of "The Dark Knight Trilogy" has made $295.2 million as of July 30, grossing a third of its Marvel competition's earnings only 10 days after its release.
