What US shows do you watch that are actually filmed in Canada? *all of them j/k X - Files (they had some American shot seasons). The Twilight Zone (that new one) What We Do In The Shadows Honey, I Shrunk the Kids: The TV Show Are the ones that I watch/watched that I know are/were filmed in Canada
All of the CW Arrowverse shows for starters. There are a ton of TV shows and movies filmed in Canada. I am sure most people watching have no idea. Super hero movies off the top of my head Deadpool, X-men, Fantastic Four, Catwoman, Suicside Squad etc...
Canada does subsidize film and TV production I think, but it seems to me I read some where that a lot of folks really like to film in and around Vancouver if they have a lot of outdoor scenes because of the number of overcast days per year. They have fewer lighting issues to deal with on set.
Resident Alien is one; I should have known that given the show's setting it feels, but it was a minor surprise when I found out, even though the only cast member I recognised is Gary Farmer and Gary Farmer's Canadian, I had no idea until I found out.
