Do you have an actor who is so compelling to you that you’ll always watch a movie they’re in, simply because of that actor?
For me, it’s Jackie Chan. His movement skills, his stunt foolhardiness, his acting ability are always worthwhile for me to watch. Even if the rest of the movie is terrible.
I’ll watch pretty much anything Leonardo DiCaprio (Leo DC to me) is in. For myself, I think at least part of my admiration is related to their film / role choices. Another actor who has way more good films than bad is Kevin Bacon
Answering what the OP actually asks, when I see Dame Helen Mirren’s name in the cast, 98% of the time I’ll check it out. I have a vague awareness that she’s been in some gangster, fast and furious whatnot, and, not even for the exquisite DHM am I going to sit through that
I choose movies based on theme or genre, not on cast. However, if I see certain actors’ names in the credits I will perk up and elevate my expectations. These include people like Saoirse Ronan, Stanley Tucci, Bill Nighy, and Olivia Colman.
Tom Hanks, Colin Firth, and Stanley Tucci.
Also Margaret Martindale and Terry O’Quinn.
I love to watch Robin Williams but it just makes me sad that he’s gone.
Limiting this to actors who are still perpendicular, Denzel Washington and Tom Hanks come to mind first. Both of them elevate whatever they are in whereas lesser actors would not.
Non-stars, but Holt McCallany and Will Patton. Two guys who most people would recognize by face but not by name. Patton many would probably recognize by just his voice. Neither are A-list main protagonist types, but both always do quality work.
Chameleon Gary Oldman. He can do the froo-froo Shakespeare roles, portray punk icon Sid Vicious, play a scary pimp in True Romance, be an ordinary schmo like Commissioner Gordon in the Dark Knight movies, and even glue on prosthetics and nail WInston Churchill.
I’ve got quite a list, which I may expand on later. One of them is James Garner, with one exception. I will never watch The Notebook because of the dementia plot point. It hits too close to home.
Sounds like “Mobland” (Paramount Plus is the streamer). I watched about 5 minutes of that and noped right out of it, even though I usually enjoy Pierce Brosnan as well as Dame Helen.
She was superb in “1923”~make sure you see that. Harrison Ford was great in that also.
