Once upon a time, movie aliens were little more than actors with their faces painted green. Then from the 1970s onwards, advances in prosthetics led to the creation of a series of iconic and entrancing extra-terrestrial beasts in films such as Ridley Scott's Alien (1979), ET (1982) and Predator (1987).

It's a trend that's reaches a kind of milestone with current hit Guardians of the Galaxy, where a sentient tree and a talking raccoon steal the show under the noses of the human actors.
