Just a few errors...
The Alien Invasion episode was Quatermass II, where the aliens descend in aerodynamic capsules and take over the population of a small village 6 miles from Carlisle ( actually Hemel Hempstead )
The only acceptable version of War of the Worlds was the 1953 version by George Pal, the 2005 remake had the wrong story, the wrong location and the wrong cast, I'm still waiting for somebody to film this true to the original book.
How you can describe any remake of Invasion of the Body Snatchers magnificientis a huge fail, nothing comes close to the original Don Siegel version.
and some you missed, on the basis of actual invasion by aliens...
Village of the Damned
Plan 9 from Outer space
and... To Serve Man by Damon Knight ( Twiglet Zone 1962 )
