Amazing interview Hicks.
One aspect of the interview that resonates with me is Cynthia describing the geography of London UK (in the 80's) and how much of ALIENS was filmed in South West London (Acton Town) and Pinewood Studios which is West of London just before Slough.
All these locations are accessible via public transport on the London Underground's (overground) service.
I recall visiting Acton Town Underground Station (above ground route) on an early sunny day in 2011 amongst quaint houses, flowery gardens near Gunnersbury Garden and the Royal Botanical gardens. I was blissfully unaware that a mere 3 miles north heading towards Harlesdon Underground station was the, now demolished, Acton Power Station where weapon carnage, APC on fire chase sequences, flamethrowers, exploding Xenomorph's, screams, chestburster and Dietrich's ALIEN nest grabbing scene were filmed!!!!!
Pinewood Studios London are a mere 14 mile, 30 minute car journey west of Acton Town, where they filmed the powerloader and colony exterior shots. Also to a lesser extent it is where ALIEN 3 was also filmed (Pinewood Studios)..
Mind blown I was always under the impression that ALIENS was filmed in the USA until I saw "Superior Firepower- the making of ALIENS". It also took me a while to realise how close I was to movie making history without even knowing it.
