Continuity: In the diner scene where Bruno commits "carbicide" the exterior light goes from night to day then back to night.
Miscellaneous: When Brüno takes OJ out of the box at the airport, the subtitles says "That is 13 pounds of black gold." He says "Das ist vierzehn Pfund schwarzes Gold." "Vierzehn" means 14, not 13 ("dreizehn").
Continuity: In the part where Brüno and Lutz are fighting outside of the police station, after Brüno says no to Lutz, there's a gold Ford Mustang in the top left hand corner of the frame, however, after it switches to the wide angle view of Lutz walking away from Brü, the same Ford Mustang drives through the entrance of the police station and is clearly not in the same spot as it was only a few seconds before.
