Spaced Invaders (1990)
Hadn't seen this in years but remembered loving it when I was younger. It's still pretty fun and it's interesting seeing the animatronics not holding up as well as you had imagined they did when you were younger. I also love the concept of aliens mistaking a broadcast of Orsen Welles' War of the Worlds for a real invasion.
I think it's also important to note that this film's director is none other than Patrick Read Johnson. The man behind 5-25-77.
