Better stock up on popcorn -- the last episode of "Lost" just got thirty-minutes more confusing complex.

According to The Hollywood Reporter, the show's producers couldn't fit everything they needed into the highly anticipated series finale -- so ABC gave them an extra half-hour to work with.

The additional running time will push back local news as well as Jimmy Kimmel's special "Aloha to Lost" episode.

The big finale airs Sunday May 23 -- from 9-1130pm.
