"Arrested Development." The cherished cult sitcom, which was canceled by Fox in 2006, has found new life in the form of a fourth season on Netflix. When the show's fans found out about the revival, many of them became so excited that they almost blue themselves.
Zombies. The scientific community is divided over whether zombies can actually be resurrected -- they do, after all, enjoy undead status. But with "The Walking Dead," "World War Z" and Amazon Studios' recently greenlit "Zombieland" pilot, they're certainly enjoying a resurgence in Hollywood.
Robert Downey, Jr. A string of drug-related arrests left this one-time Hollywood whiz kid's career teetering over the abyss. But look at him now. He's Iron Man. Are you Iron Man? Yeah, we didn't think so. (Photo: Getty Images)
Attacks on the White House. In the pre-9/11 days, a moviegoer could look forward to hitting the theater, buying some popcorn, and watching 1600 Penn get blown to smithereens in "Independence Day." This year, films like "Olympus Has Fallen" and "White House Down" (directed by "Independence Day" helmsman Roland Emmerich) are ready to decimate the president's pad once again. Who says Hollywood is in Obama's pocket?
"Veronica Mars." Thanks to a massively successful Kickstarter campaign, Kristen Bell's series about a scrappy female private investigator.
"Dallas." The massively popular nighttime soap found new life -- and impressive ratings -- with a TNT revamp last year. Sadly, it probably won't be possible to resurrect recently deceased star Larry Hagman, who gave the world one of TV's most enduring villains in J.R. Ewing.
Charlie Sheen. Sheen nearly torpedoed his own career when a run of bizarre behavior got him tossed off of the successful CBS sitcom "Two and a Half Men." But now he's found a second life on FX's "Anger Management." The only downside? His career resurgence sometimes brings him into contact with Lindsay Lohan.
3D. Once a theatrical novelty (and occasional headache-inducer), 3D is now a serious force, and an easy way for studios to wring a few more bucks out of moviegoers. Even the remake of "The Great Gatsby" is being made in 3D -- which really ought to make the Hamptons decadence pop right out at you. (Photo: Getty Images)
"Star Wars." After purchasing Luscasfilm, Disney is bringing the epic sci-fi franchise back from the dead with a series of new movies. Hopefully they'll leave Jar Jar Binks in the tomb.
Brett Ratner. After he uttered a homophobic slur at a screening of his movie "Tower Heist," Ratner caused an uproar and resigned from producing the 2012 Oscars. But after making apologies (and the "Coming Out for Equality" PSA campaign), Ratner received GLAAD's Ally Award this year. (Photo: Getty Images)
