After the sexual misconduct allegations came out against Kevin Spacey, the fate of "House of Cards" was plunged into doubt. As we write this, there has still been no official word on whether it will be cancelled, or if "House of Cards" will move forward without main character Frank Underwood.
But canning the lead actor is far from the most extreme situation a show could face. Plenty of shows have backed away from the cliff over worse -- Heck, some have even been resuscitated after cancellation. Check out the gallery below to see shows that were on the brink of (possible) cancellation for one reason or another, and the last-ditch efforts that were made to save them.
"Once Upon A Time" Almost every key regular decided to leave after they show's sixth season. It looked like all might be lost, but producers opted for a soft reboot that kept it going.
"Community"The cult show spent its life on NBC perpetually on the bubble until the network finally cancelled it after season 5. Yahoo Screen picked up the cancelled series soon after; Fans got their "six seasons," now they just need the "and a movie" part.
"Chuck"Fans rescued the show by getting advertiser Subway involved with a "Save Chuck" campaign that actually worked.
"Friday Night Lights" A deal NBC struck to have DirecTV produce the show kept the Panthers playing for several seasons.
"Buffy the Vampire Slayer" The WB didn't put a stake through "Buffy"s heart, but the network wasn't willing to shell out the cash UPN was for the series -- so it jumped networks.
"The Leftovers"Die-hard fans showed up at the network's headquarters in NYC dressed as the show's Guilty Remnant faction, which was good enough for HBO.
"Nashville"ABC denied the country musician-centric show a fifth season, so CMT stepped up and brought it to a new home where it was truly appreciated.
Star TrekA story so nice we'll tell it twice: What became one of the most influential shows of all time was a low-rated cult hit when it originally aired. It was almost cancelled after its second season, but an intense letter writing campaign by the show's dedicated fans convinced NBC to give it a third season -- after which it was canceled for good.The show went into syndication in the 1970s where it became a truly monster hit. The show was revived as a film series in 1979, which in turn spawned a sequel television series, "Star Trek: The Next Generation" in 1987.
"Baywatch" The original run from 1989-90 suffered from poor ratings and a studio shutdown, but David Hasselhoff and the creators helped get the show into syndication.
20th Century Fox Television
"Roswell" The WB let "Roswell" live after fans sent in bottles of Tabasco sauce (the characters' favorite condiment) to beg the network not to cancel.
"Jericho"Fans took a main character shouting “nuts” to heart and sent CBS studio executives tons of the snack. Lucky for them, they reviewed the ratings and renewed it.
"Arrested Development" Fans thought the Bluth Family was gone for good when Fox canceled the show in 2006, however, Netflix picked it up for a fourth season in 2013 and its still going.
ValerieSimply put, one of the most infamous cast shake-ups in sitcom history. Star Valerie Harper, for whom the show was created and named, was fired after the second season, and her character killed off, over a fight with NBC and the show's producers over pay. (This would lead to a bitter lawsuit Harper eventually won.)Instead of canceling the hit show, NBC retitled it "Valerie's Family" for season three, and "The Hogan Family" from season 4 on.
