The Foo Chow is a real restaurant in Chinatown. As of August 2024, there is still a sign that states, "...Rush Hour was shot here".

The ransom of $50 million, in the denominations requested by the kidnapper, would total 2,400,000 individual bills. That amount would never fit into two suitcases. Moreover, that amount of money would weigh more than 5200 pounds.

Outtakes from the film play during the end credits.

When aired on television on TBS in 2001, the following alterations were made: usage of the word 'shit' was completely removed and replaced by 'stuff','it', etc., the usage of the word 'ass' was limited; The scene at the police station where Carter apologizes to Johnson for spreading rumors at Christmas about them sleeping together and Johnson is enraged, the part where Lee stops her and says that Carter was just kidding and also notices his hands are on Johnson's breasts was removed; when Johnson and Lee come to Soo Yung's aide in the van, Johnson's sentence of 'it'll blow if I take it off' was removed; many of the outtakes were removed and shortened, like Jackie Chan's "My daddy cotcha bullet by his bare hands, no bullshit." was shortened; at the beginning where Clive shows Carter some C4 in his trunk, Carter's response of 'the Iraqis can't even get this shit' was altered (by replacing 'Iraqis' with Americans and removing the word shit). Also at the beginning and endings of the commercial breaks, interviews with Jackie Chan and Chris Tucker and scenes from Rush Hour 2 were shown. Jackie and Chris discussed working on the movie and commenting on each other.
