Weekend box-office sluggishness got you down? Oh. Well, either way, fortune tellers around Hollywood are saying the recent Avengers buzz has further heated up an already scorching prospect: Some tracking reports have Joss Whedon's Marvel-hero mash-up sailing beyond The Dark Knight's $158 million three-day mark from 2008, though Harry Potter and the Deathly Hallows - Part 2's all-time record of $169 million seems safe, 3-D and all. Stay tuned to Movieline for more box-office previews and projections — especially your own — as The Avenegers' May 4 release date draws near. [THR]
