Veronica Mars  may be getting all the attention lately, but it's not the only show to be given a second chance after cancellation. While the Entourage movie has finally begun production, NBC has announced it has plans to reboot Heroes for a miniseries, and the cult comedy Pushing Daisies is gearing up for a musical. Here's a look at all the shows we lost and then found again.
Despite only lasting one season, Firefly remains an integral part of the Joss Whedon universe. The 2002 sci-fi series starring Nathan Fillion, Gina Torres, and Alan Tudyk was made into a movie called Serenity in 2005.
Lee Pace , Anna Friel, and Kristin Chenoweth  star in the two-season wonder that is Pushing Daisies. Recently, it was announced that the long-buried show about a pie maker with powers to bring back the dead will be adapted into a Broadway musical .
Ah, the strange case of Scrubs. The medical comedy was a hit on NBC, but the network chose not to renew the show after its seventh season. ABC swooped in and aired two more seasons with new cast members including Eliza Coupe (Happy Endings) and Dave Franco.
Cougar Town is the little show that could. The Courteney Cox-starring comedy aired for three seasons on ABC but was constantly on the bubble of cancellation due to schedule changes and poor ratings. TBS saved the show, picking it up for a fourth and fifth season, which is currently airing.
Despite Emmy nominations and a heavyweight star as its lead, Glenn Close's Damages ended its run on FX after three seasons. Luckily for fans, DirecTV resurrected the show for another two seasons.
Beavis and Butt-Head
Mike Judge's grown-up cartoon aired on MTV for four years in the early '90s. It lived on in the pop culture lexicon and returned to the network with new episodes in 2011.

After rumblings for years, HBO's Entourage is finally getting a movie based on the series that ran from 2004 to 2011. The cast is currently shooting the film , and the feature is due out in June of next year.
FX's The Killing, aka The Show That Cannot Be Killed, was canceled after two seasons. After negotiations, the network aired a third season but then canceled the show again. Despite the drop in viewership, Netflix picked up the series and plans to air a fourth season of six episodes.

Sex and the City
Sex and the City was such a huge hit for HBO that of course it couldn't just end after the show concluded in 2004. Creator Michael Patrick King revived the show for a 2008 movie and a less critically acclaimed sequel in 2010.
It's hard to imagine Seth MacFarlane's flagship show being canceled, but that's exactly what happened in 2001, after three seasons. Fox brought the series back with new episodes two years later, after impressive DVD sales and high ratings on syndicated reruns.
Perhaps the ultimate cult hit, Arrested Development only aired for three seasons on Fox. Due to popular demand, creator Mitch Hurwitz brought the show back for one season on Netflix. Despite poor reviews for the latest season, rumors of a movie are still flying.
Fox's intense action thriller 24 aired for eight seasons before ending in 2010. In May of this year, the series will return as a 12-episode reboot called 24: Live Another Day.
Heroes was a bona fide hit when it premiered in 2006, but due to dwindling ratings, NBC canceled the show after four seasons. We thought it was over, but last month, NBC announced it would be airing Heroes Reborn , an "event miniseries" that will debut next year.
If only Veronica Mars fans actually watched the show when it was on from 2004 to 2007, the detective series might still be running. Thankfully, creator Rob Thomas and star Kristen Bell  rallied "Marshmallows" to contribute to a historic Kickstarter campaign , and the movie is due out next week!
