McKellen has been in the acting scene for over 60 years now and has been credited in over 120 films and series. One of his most iconic roles is, of course, Gandalf in the Lord of the Rings and Hobbit series, where he plays a renowned wizard who helps restore peace to the land. In contrast, McKellen also plays Magneto, one of the key villains in the X-Men universe (though Magneto does develop other roles, so much that he also becomes a superhero and an ally to the X-Men, but I digress).
