The network said Tuesday that the season finales for each of its three most popular scripted series -- "Lost," "Desperate Housewives" and "Grey's Anatomy" -- will run two hours. So will the season ender for "Boston Legal." And "Extreme Makeover: Home Edition" and "America's Funniest Home Videos." And the series finale of "Alias"? Yep, two hours. There will be a couple of regular-length finales as well, for "What About Brian" and "Invasion." As for what actually will happen during those extra-long episodes, we don't know. ABC is thus far keeping quiet on the season-ending details for all the aforementioned shows. All those extra hours means ABC will have to play around with its schedule some during May sweeps. "Brian" will end its season Monday, May 8 after just five episodes to make way for the "Grey's Anatomy" finale, the first of the two-hour extravaganzas. It will air over two nights: Sunday, May 14 and Monday, May 15. "Boston Legal" will end its season the next night. On Sunday, May 21, "Home Edition" and "Desperate Housewives" will both finish their seasons in extended fashion, with the former airing at 7 p.m. ET and the latter at 9. The fun continues May 22, when "Alias" will finish its five-year run on the network -- a switch from the Wednesday timeslot it will occupy on its return to the schedule next month. The move to Monday for "Alias" gets it out of the way of "American Idol's" final week and also makes room for "Lost" to finish the year with two hours' worth of mystery on Wednesday, May 24. "Lost" also had a two-hour finale last spring. The "America's Funniest Home Videos" season-ender on Friday, May 19, will also celebrate the show's status as the longest-running entertainment program in ABC history. It premiered in 1990. "Invasion" will end its season Wednesday, May 17. ABC also says that the long-gestating movie "Stephen King's Desperation" will air Thursday, May 18.
