Would you swim with a 30 ton whale shark, 50 feet long and with a mouth five-feet wide - the largest fish in the world?
Krov and Ann Menuhin - husband and wife film partners in underwater adventure - did just that, and more. In the Gulf of California they cruise and dive in one of the richest but least-known seas of the world. They meet huge grey whales, basking sharks, dive-bombing pelicans and the rare blue whale. They join the sea-lions' graceful ballet - and then encounter the gigantic whale shark.

In this latter-day version of The Scarlet Pimpernel, Leslie Howard stars as a seemingly vague professor, carrying out research in Germany. In reality he is rescuing potential victims of the Nazis. Irony, humour and romance are blended into this exciting drama.
The film, produced and directed by its star, is being shown as a complement to the tribute to Leslie Howard , featured in the BBC1 season The British Greats.
