Other mistake: When Marshall returns from Minnesota, he approaches Lily lying on the couch from the kitchen area rather than from the door, and Lily still acts surprised to see him, even when he was obviously already in the apartment with her.

1 other mistake in Desperation Day - chronological order
Starring: Jason Segel, Neil Patrick Harris, Cobie Smulders, Alyson Hannigan, Josh Radnor
Revealing mistake: While showing the clip of Marshall streaking the first time, you can see thumbnails for videos of him streaking in New York. Those videos were created later that day and could not already be posted. One also shows a woman in yellow and appears to be a retake of the scene. (00:06:15)
