SUPERHERO FILMS might not top the year’s box office returns — Hogwarts, Forks and Zach Galifianakis all have ‘em beat — but the cinematic Spandex is reigning omnipotent on one movie list:

Twitter’s Hot Topic Movies for 2011.

Second on the Hot Topic Movies list is Warner Bros./DC’s “The Dark Knight Rises” — no mean feat considering the film isn’t out till the middle of 2012 — and the film’s Selina Kyle/Catwoman, Oscars co-host Anne Hathaway, also cracked the Hot Top Actress list.

The third Hot Topic Movie is another one to make Stan Lee happy: Fox’s ”X-Men: First Class” — thought neither James MacAvoy nor Michael Fassbender was able to make Twitter’s Actor list. And fifth was Sony’s underperforming “The Green Hornet,” which at less than $100-mill didn’t even crack the year’s top-25 films in domestic gross.

Fourth on the Hot Topic list was the lone exception to the trend: Universal’s “Fast Five” — the latest in that unkillable fast-and-furious franchise.

“Thor,” “Fast Five” and “X-Men” — as well as “Captain America: The First Avenger” — all grossed more than $140-million domestically to rank among the year’s top-15 films.

Yet not even Cap could top one celebrity’s personal Super Serum:

The No.-2 Top Hashtag of the year was...Charlie Sheen’s #tigerblood.
