Name our new robot!
To celebrate our 100th birthday we have created a new character. Like all films when the BBFC was invented in 1912 he is in black and white, rather than colour.
In those days films were silent too. That's why he holds up a sign instead of talking in speech bubbles like Oskar.
We need your help though. We don't know what to call him? Would you like to vote for a name for him? Go to our voting booth (on the home page) and select which name you like the best.
