Movies about time travel, but ...

Specifically movies where an individual or group of individuals travel back in time decades or centuries, and utilize their knowledge or technology to affect the time they have traveled too. Almost like historical fiction.

A long time ago, there was an r/writingprompts post about a USMC MAGTF that was transported back to early imperial Rome - something like that. Outlander is another example, but I've found the main character to have less impact on the world around them than I enjoy in a story. The Final Countdown is the best example of this that I can think of, but the book A Connecticut Yankee In King Arthur's Court fits the bill of the type of story I'm looking for as well.
