In the great big battle of the summer superhero movies, The Avengers has just toppled a record previously held by The Dark Knight Rises. The latest Avengers movie trailer was released on iTunes on Wednesday, February 29, and it was viewed over 13.7 million times in the first 24 hours. The 13.7 million views was enough to set a new record for the most viewed trailer on iTunes. The previous record was held by a Dark Knight Rises trailer, which racked up 12.5 million views in its first 24 hours. Back in December, The Dark Knight Rises trailer broke the record that was previously held by none other than the first Avengers trailer, which had 10 million views in its first 24 hours. While both The Avengers and The Dark Knight Rises will likely do very well at the box office, competition appears to be fierce between the two to earn the bragging rights of being the top movie of 2012. In the press release issued by Warner Bros. when The Dark Knight Rises broke the record, they made an obvious dig at The Avengers, by pointing out that it broke "the previous record by well over two million." In the press release from Marvel Studios, they take their own dig at The Dark Knight Rises by describing The Avengers as "this summer's most highly anticipated movie." Marvel's The Avengers stars Iron Man (Robert Downey, Jr.), Captain America (Chris Evans), Hulk (Mark Ruffalo), Thor (Chris Hemsworth), Black Widow (Scarlett Johansson) and Hawkeye (Jeremy Renner), Nick Fury (Samuel L. Jackson), and Loki (Tom Hiddleston). The movie is produced by Kevin Feige and directed by Joss Whedon from a story by Zak Penn and Joss Whedon with the screenplay by Joss Whedon. Marvel's The Avengers is scheduled to be released in U.S. theaters on May 4, 2012.
