Lord of the Rings Could Have Given the Fellowship a Powerful Ally, but He Wasn't There When We Needed Him Most
Radagast the Brown is one of the most powerful wizards in The Lord of the Rings, but he was absent during the War of the Ring on Middle-earth.

The Lord of the Rings tells the story of a dangerous time in Middle-earth. With Sauron gaining power, everyone bands together to fight back. Men and Elves fight side by side, Hobbits leave the Shire, and even the Ents go to war. But among the many powerful characters in the fictional world, the five wizards are among the most impressive. Known as the Istari, these individuals are Maiar sent to Middle-earth by the Valar to oppose Sauron – which is what the War of the Ring is about. Yet only two of them are seen in the films. Gandalf (Ian McKellen) and Saruman (Christopher Lee) play major roles, with Gandalf being part of the Fellowship and Saruman fighting against them. There is an excuse for the Blue Wizards' absence, as they have been missing for many years. But the final Istar, Radagast the Brown (Sylvester McCoy), is somewhere in Middle-earth but doesn't show up at all.
