Alien attack?

In my class we watched a Vancouver film school video. It was called ‘Alien Attack?’ I think it was amazing, cool and very funny. Firstly an alien landed on a  strange planet,  then he saw a cactus. He signalled the come on sign to the cactus and expected  him to follow but of course he was a cactus so didn’t move. In the end he vanished into thin air. But it just shows that things aren’t always expected.
