His agents must be dying. Dominic Monaghan has a blue-chip acting career—topped by The Lord of the Rings trilogy and the TV phenom Lost—yet he's risking it all for Wild Things With Dominic Monaghan. The new BBC America nature series (premiering Tuesday at 10/9c) finds the Brit star trekking through Asia, Africa and South America in search of creepy creatures — flesh-ripping ants, giant carnivore centipedes, waterbugs that turn their prey to liquid. And he'll merrily rappel into subterranean, snake-filled caves or swim in a croc-infested waters. Is he nuts? No, just fearless.
