#43. The Lord Of The Rings: The Fellowship Of The Ring

Released in 2001, The Fellowship of the Ring is the first installment of the legendary, record-breaking film franchise. It received a whopping 13 Academy Award nominations, of which it won 4. But you know what they say, even geniuses make mistakes, so let’s see the silly mistake made by the genius who played Gandalf, Ian McKellen.
In one of the opening scenes, Gandalf and Frodo pay a visit to Bilbo who, just like the rest of the hobbits, lives in a ridiculously small house. Gandalf hits his head against the roof and grabs his head in pain, but actually, that wasn’t in the script! However, McKellen stayed in character, so the director left the scene as it was.
