The already hefty ensemble for action/comedy sequel Red 2 is growing by one. Director Dean Parisot has zeroed in on Harry Potter veteran David Thewlis to tackle a small role.

Thewlis is signed on to play The Frog, an information dealer and lowlife shyster who got his nickname after poisoning the water supply at the Kremlin with the venom of a poisonous Amazonian amphibian.

He’ll be part of the sequel’s plot, which finds Bruce Willis’ Frank Moses, John Malkovich’s Marin Boggs and Helen Mirren’s Victoria brought out of hiding to deal with an even bigger threat than the one they faced last time, which will see them travelling in Europe as well as the US.

Fellow new arrivals this time include Anthony Hopkins, Catherine Zeta-Jones, Byung-hun Lee and Neal McDonough.

Parisot is looking to begin shooting later this autumn in Montreal. Jon and Erich Hoeber, who wrote the script for the first film based on Warren Ellis’ and Cully Hamner’s graphic novel, are back on screenplay duty for what we expect will be another round of explosions, car chases and Bruce Willis cracking wise / showing the young ‘uns how it’s done.
