Filming locations -- then and now
The first one - an episode of Horror's Hallowed Grounds (around 20 mins) - is a guided tour (included as an extra on Second Sight's TCSM Blu-ray). The second one (six minutes) is a series of split-screen comparisons with no commentary. The third (eight minutes) is a tour of the TCSM 'murder house' with Gunnar Hansen (and, like the first, is on the Blu-ray)
