The building is falling apart, the rubble is piling up, the mothership is approaching, the clock is ticking down: "Let's get out of here!"
Yeah, that one especially. Problem is, a lot of these cliche lines are treated by writers as being as expected as "your welcome" is the only response to "thank you".
Also:
"Nobody can stop me!" - said by the villain just minutes before the villain is stopped
"Don't do anything stupid!" - said by cops when cornering a suspect, just before the suspect does something stupid
