Freddie as F.R.O.7.

Freddie as F.R.O.7. (also titled Freddie the Frog) is a 1992 British animated movie about an anthropomorphic frog who becomes a secret agent. The film stars Ben Kingsley as the voice of Freddie, with additional voices provided by Jenny Agutter, Brian Blessed, and Nigel Hawthorne. Designed as a big-budget summer blockbuster, the film did poorly at the box office and, for a time, held the U.S. record for the lowest-grossing animated film of all time.

Plot
Cursed to live as a frog by his evil aunt Messina (Billie Whitelaw), Freddie (Kingsley) grows up to become a valued member of the French Secret Service. He is sent to London to investigate the mysterious theft of landmarks there, teaming up with British agents Daffers (Agutter) and Scotty (John Sessions). Freddie learns that the villain responsible is El Supremo (Blessed), who is stealing the landmarks with the help of Messina and a secret army.

Freddie deduces that Big Ben will be the next landmark stolen; he hides inside it with Daffers and Scotty and is taken to El Supremo's lair when it is stolen. There, Freddie and Scotty are fed to sea monsters while Daffers is brainwashed into becoming a mindless follower of Messina. Freddie and Scotty escape the sea monsters with the help of Nessie, the Loch Ness Monster (an old friend of Freddie). They rescue Daffers and put an end to El Supremo's plans.
