Martin Freeman reprised his Office role as Tim, well sort of. He was also ilbo Baggins at the same time.
This Saturday Night Live sketch was perfectly executed, you had Gandalf as David Brent, Smeagle as Gareth and of course Martin Freeman as both Bilbo Baggins and Tim. It’s a complicated mix to explain but I’m sure you get it.
They managed to pull it off so well by making classic references to both titles, seriously, it really works. See for yourself.
