Okay, E.T. isn’t strictly a Christmas movie, but you would have to have a heart of stone to fail to appreciate its heart-warming awesomeness in the season of eating, drinking and being merry with family.

In case you are from E.T.’s home planet, and have never come across E.T. the movie, you should know that this is a Steven Spielberg family classic. A troubled child called Elliott summons the courage to help a friendly alien escape Earth and return to his home world. Drew Barrymore takes her bow, and once you have wiped away your tears you will feel that all is well with the world. As indeed it will be.

Every family Christmas should include a group viewing of E.T. It won four Oscars and that is many too few. Here we explain how to watch E.T. - The Extra-Terrestrial online, on TV or on any mobile device. (See also 'How to watch every Christmas movie online'.)
