Lethal Weapon 2

During production, Richard Donner was shocked when Mel Gibson confided that he was drinking five pints of beer for breakfast. Despite his alcohol problems, Gibson was known for his professionalism and punctuality.

People with diplomatic immunity do not have automatic carte-blanche to commit any crime without punishment. If a person with diplomatic immunity commits a crime, law enforcement has to contact the host country, then the diplomat either has his immunity revoked for trial or gets deported back to their own country to face consequences there.

This is an obvious example of artistic license, and thus is not a goof as per IMDB guidelines.

The Merrie Melodies theme is briefly heard during the opening sequence.

To receive a 15 certificate, the UK cinema version was cut by the BBFC. These cuts included:

• Reduced violence in the scene where Murtaugh kills two thugs with a nail gun (a shot showing blood on a thug's head was shortened and another showing nails embedded in the other thug's chest was optically darkened).
• Most of the sex scene between Riggs and his girlfriend was cut.
• Riggs' vengeful killing of the villains who killed his girlfriend on the pier was entirely cut.
• Riggs' repeated shooting of a villain during the final shootout was reduced.
• Kicks to Riggs' face by villain in climax were reduced.

Later video and DVD releases had some cuts waived but were raised to an 18, whilst retaining the edits of the pier killing and repeated shooting of a villain by Riggs. The cuts were fully waived in 2010 and the certificate downgraded to a 15. The uncut version is only available on Blu-Ray, while the DVD still has an 18 certificate but is missing the killing of the two thugs on the pier and of the guards on the container.
