The 1943 film Air Raid Wardens had LandH walking in front of the church Bob and Millie Frazer go into in Stopover in a Quiet Town to unsuccessfully call for townspeople. Both Air Raid Wardens and TZ were filmed on the MGM backlot.

Another film (an educational one) L+H made called Tree in a Testtube may or may not have been filmed on the MGM studio backlot as well.

I believe someone at the TZ Cafe webpage saw my posting here and commented on it over there 10 years ago.
