It's V. For people who don't know, V was a Sci-if Mini-series from 1983 which was kinda a 2 part TV movie, then a 3 part Mini-series which followed it up and finished the story. Then a cheap-ish slightly lackluster TV series which ended on a cliffhanger which never got picked up (and one of the writers ideas for the second series would have been... very crap).. there were also a series of books which follow up from the mini-series but doesn't include the TV series. so in total, ran from 1983 to 1985. (there was some god awful 'we wanna piss on the fans' remake in the 2000s but.. no.. don't anyone dare mention that awful insult.. the kinda thing which just nicked a few names and made something completely unrelated).
It was about a race of human looking aliens who come to earth claiming there planet is dying because of lack of water. At first, they appear to help humans and humans help them, but it turns out they are in fact a race of lizard like creatures who want humans for a food source and are currently at war with another alien race. There are a lot of.. clear but not stupidly done Nazi references (red Uniforms with Black Logo, the 'Visitor youth', a Jewish couple who remember the war etc. Good actors, good work.. much less so on the series where they had money issues and even kinda soft rebooted the show half way through.
Robert Englund was one of the kinda main side-line Aliens, giving the earth name 'Willie' in the TV 2 parter and the mini-series. He became more major in the TV series as the 'friendly alien' as, like with some of the aliens, he wasn't as nasty as some of the higher ups and ended up siding with the humans (who some weren't quite as nice.. not just because they are siding with aliens or anything.. some just.. aren't nice people). Robert Englund used to do a lot of good acting roles but then kinda seamed to get stuck doing heavy makeup horror films, such as Nightmare on Elm street where.. not saying he didn't do a good job but alot more limited range. And of course, with such heavy makeup, you can get away with a flop or anything else cause no-one knows your face.
