On May 1 Weakest Link will be airing a new episode an hour later than usual at 10:00/9:00 instead of 9:00/8:00. This is because of a 3 hour movie NBC is airing from 7-10. The following Sunday on Mother's Day, Weakest Link is preempted for Saturday Night Live, then returns to its regular time on May 15.

Correction: Weakest Link is also preempted on May 15 for the Billboard Music Awards. Weakest Link returns new on May 22 and May 29, this time at an earlier hour of 8:00/7:00.

Now Futon is listing May 22 and May 29 as repeats. Then Weakest Link returns with new episodes Monday, May 30 at 10:00, supposedly new every Monday through August 15 except for July 4.
