18. Brad Dourif (Grima Wormtongue)
Brad Dourif is perhaps best known for voicing Child’s Play’s evil doll Chucky, but he’s played several other memorably creepy characters throughout his career. His role as the corrupted Grima Wormtongue in LotR, for example, stands out for many as his definitive performance. The star has worked steadily in the intervening years, too, and he will reprise Chucky for the seventh time in 2017.
17. Bernard Hill (King Theoden)
Despite being gripped by the ring’s all-consuming power at the start of the The Two Towers, King Theoden eventually became one of the series’ most hardened heroes. And certainly, the character’s transformation was only possible due to the talents of Bernard Hill – the actor who fleshed out the role in the second and final parts of the trilogy. Following the series’ success, meanwhile, Hill continued playing supporting roles, including a turn in the BBC series Wolf Hall.
16. Andy Serkis (Gollum)
Although slated solely to provide slimy hobbit Gollum’s voice, Andy Serkis’ physical audition left a big impression on director Peter Jackson. As a result, the actor played the character through motion capture technology and ushered in a new age of digitally enhanced acting in the process. Now Serkis is famed for his mo-cap roles and has fleshed out further CGI creations in Rise of the Planet of the Apes and King Kong.
