While the original title, "" isn't a misnomer, it was a bit misleading since the "trailer" is a dog named Caesar and the killer is a mountain lion, aka as a cougar or puma the narrator was quick to point out. But the makers also pointed out that Caesar "is the most intelligent dog actor since Rin-Tin-Tin" which probably lured a few Rin-Tin-Tin fans with a show-me attitude. Caesar prowls around the woods of the Northwest, dispatches a rattlesnake, visits his she-wolf mate and their pups, pauses to watch the dainty habits of a raccoon personally washing every morsel of food before eating it---and that raccoon had enough food to use up several minutes of running time---and then saves sheepherder Pierre (Francis McDonald) from getting et up by one mean mountain lion. Rin-Tin-Tin he ain't, but then who was? Commonwealth changed the title to "Call of the Wilderness" when they acquired it for 16mm rental to the school market.

How to Watch Trailing the Killer Legally and Safely

If you want to stream Trailing the Killer through reputable and legal services, there are a few good options depending on where you are. Subscription platforms like HBO Max, Disney+, Netflix, Amazon Prime Video, and Apple TV+ sometimes carry Trailing the Killer films or related DC titles—though availability depends on your country.

If you’d rather not commit to a subscription, there are ad‑supported, free (but legal) platforms such as Tubi, Pluto TV, Peacock or Crackle (where available in your region) that occasionally host superhero films.

Lastly, don’t forget about library‑linked streaming options like Kanopy or Hoopla (if your library or university is registered), and official uploads by film distributors on YouTube—these can also give you legal access to classic movies.
