I remember this interview way back when it originally aired in 1988. Jamie Lee Curtis is just embarrassing to watch, trying to be funny. Especially after the 12:20 mark when she's pretending to be bored by Cleese, leaning on him, pretending to be going to sleep. Cringe. Meanwhile, Cleese and Palin are bouncing jokes off of everyone and each other and being really witty and truly funny. Its as if they stepped foot off the Monty Python set only 10 minutes earlier as opposed to 15 years earlier.
This entire cast from "A Fish Called Wanda" -- John Cleese, Jamie Lee Curtis, Kevin Kline and Michael Palin -- appear on the American talk show "Donahue." Great fun and hilarity ensues (but no silly walks). Enjoy this home-archived video from Thursday September 1, 1988.
