Slap shot - Paul Newman, comedy, hockey, nuff said. 
Life of Brian - Monty Python’s best IMHO
Best in Show - I generally don’t watch movies with animals, but...

this is very real

"If", 1968

"King of Hearts", 1966

Both are commentaries on war.

Recently watched "Once Upon a Time in Hollywood" and after not caring for DiCaprio for years I finely liked him in a part.

Also enjoyed the "what if" justice of the film.

"Gunga Din", 1939 - was more entertaining than I recalled (watched it a couple months ago).

This upsets my wife...

I’ve recently been recording Steven Seagal movies off cable and then giving them a try (FF and Delete are my friends in this case).

I had no idea that he made so many (FITB) movies.

Aside from movies I recorded and watched "The Office" TV series in its entirety (in order).

Starting to do the same thing with "Bob’s Burgers" an animated series.

Also recorded 11 seasons of "Midsummers Murders" (British TV series) and am finally starting season 11.

Having trouble recalling the titles of the movies watched since being shut-ins, but there may be a history stored in the cable/satellite box.

PS:

"Ford VS Ferrari" was really good, and I'm not a car guy.
