"The In-Laws is the funniest comedy I've ever seen. It doesn't matter how many times I see it, it still feels fresh and makes me laugh as if for the first time. In fact, it has got funnier with time. Parts of the script have even become in-jokes for my entire family. A marvellous script with the perfect cast - beautifully executed - makes this one of those films that deserves to sit with the best comedies of all time. It's all played for real, not for laughs but the characters have been created with comedic flair and imagination; Peter Falk steals every scene, while Alan Arkin, his total nemesis, is wonderful as the unwilling accomplice.

 

There are so many memorable scenes and situation, but my favourite is at the conclusion of the fabulous flight sequence that Andrew describes above, when Vince instructs Sheldon to 'serpentine' from the plane, through the flying bullets to the safety of the waiting car. Its bizarre nature typifies what the film is all about Special mention to dentists, who will enjoy the scene when Sheldon is absconded from his dental surgery, while a patient waits (for a very long time) with mouth wide open, while a cast hardens. Clever, wacky and very, very funny, The In-Laws is the best in-joke for movie lovers."
