The bartender finishes pouring the two double tequila shots twice.

At the end of the movie when Steckler is chasing Mace through the crowd there is one time when the film is reversed. Steckler's badge appears on the wrong side of his body and his gun has changed hands.

Just before Lenny and Mace get into the "Millennium" party, a screen shows people celebrating the new year in Madrid, where it is still dark. This is not possible as the time in the movie is just after 11:00 p.m., which means that it is after 8:00 a.m. in Madrid

The new millennium began on January 1, 2001, not on January 1, 2000, which was the last year of the twentieth century (due to factors such as year 'zero' never existing). However, when the time came, most of the world ignored the fact and chose to have the big celebration on December 31, 1999.

The safety cable is visible during the final 10 or 20 feet of Max's fall.

When Faith's handcuffs are supposedly being removed, it's clearly visible that she isn't cuffed anymore and that she just kept her hands close to the bed frame, while the unknown person pretends fumbling with the cuffs that are not there. He then picks them up from somewhere behind the bed frame so that it looks as if he just removed the handcuffs from her wrists.

After Lenny and Max fight in the hotel room, and the glass doors are shattered, all the shattered glass appears to be swept neatly off to the side as Lenny is walking away,.

During the final showdown when Angela Bassett strikes Vincent D'Onofrio, with the police baton, it is clearly rubber as it is bent afterwards.

After Lenny leaves Twitch's various bits of music play as he cycles through stations. There are 2 mistakes made in this sequence. First the digital readout is in frame more than once but number showing what station he is on doesn't even when he changes the channel. Second mistake being one station is playing "Get Your Gunn" by Marilyn Manson along with listener call in and the word "fuck" in the song is clearly audible when it most certainly would be bleeped out for radio play.

The pre-recorded clip of Lenny watching himself in a mirror shows him in profile, not from directly in front.

The military is using a M41 Walker Bulldog tank, which was retired in the 1960s.

When Lornette and Lenny are in her house and she has him pinned against the wall, you can hear her voice but her mouth is not moving.
