do you remember when ...

[Jack Lord]

I love when they are doing an actual outdoor shot, like the guys getting off their horses, then immediately walk over to a rock or tree on an obvious soundstage with the fake background and plants.

Yea that always made me chuckle.

Even more silly and still seen is when a show is supposed to be based somewhere like Washington or Philly, but you see palm trees in the background revealing that it is actually California. I remember watching a chase scene in the Six Million Dollar Man where they were racing through downtown DC past all the palms of Sunset Boulevard. My dad yelled, "That's not DC!".
