Probably Boris Karloff or Vincent Price or maybe even Lon Chaney Jr? Most horror films or horror franchises?

While I agree that they are in a lot of horror movies, I'm not sure they are in a lot of franchises.

Price has Phibes and Invisible Man.

Karloff has Frankenstein and... uh...

Chaney Jr. has Dracula, Frankenstein, Wolfman, Mummy...

Karloff was also in The Mummy. Price was in The Fly. Christopher Lee and Cushing probably also qualify for all the Hammer remakes they were both in.

Noted on Karloff and Price. So what do those others have?

Cushing: Dracula, Frankenstein, Mummy, Phibes, I guess Tales from the Crypt...

Lee: Dracula, Frankenstein, Mummy, Dark Shadows (shitty 2012 movie), uh.......

I would have to research it but they were both in The 2 Faces of Dr Jekyll off the top of my head. Also, what do you constitute a "franchise"?... any film that was given a sequel and/or a remake? Cause I definitely wouldn't consider Urban Legend a "franchise."

Franchise = Series, more than one movie

The definition can get a little iffy sometimes in regards to certain vintage characters like Dracula and Frankenstein and in your example, Jekyll and Hyde. Like Dracula as a franchise wouldn't include every Dracula movie, but rather Universal Dracula. Or Hammer Dracula. So something like Horror of Frankenstein, even if its kind of a stand alone thing, would count towards the Hammer Frankenstein franchise.

I'm not sure Jekyll and Hyde would count as a franchise since that character is public domain. All the movies I know of are simply adaptions by various companies. 1931 is Paramount, 1941 is MGM, so there's no real connectivity there.

Urban Legend has 4 movies in the series, so yeah. Definitely a franchise.

I don't believe you...there can't be 4 Urban Legend films. I don't think I wanna live in a reality where there is 3 Urban Legend films. I remember playing the Gong Show with 2 somewhere close to midway saying to myself, how did that POS ever get a sequel greenlit? Oh yeah....fn Scream. At least with I Know What You Did Last Summer I got to zone out drooling at Jennifer Love Hewitt for 90 min.

JLH was hot in those movies...

But yeah, at least 3 Urban Legends. IMDb lists that third sequel under a different title, but at the very least, 3 movies in that series.

I remember in school, people would refer to JLH as "Jennifer Love Huge Tits". I did appreciate those a lot back in the day, but it's funny how my definition of 'huge' has changed over the years.

Dude, I watched Heartbreakers recently, just thinking about her in that film...fnck, I spilt my...that might stain...I gotta go finish rubbing this out now. I'll be back later.

Uh...Spilt my cocktail on my new carpet. Don't rub, gotta blott that sh!t out!

Brad Dourif was also in The Exorcist III.

dee wallace tends to put it about a lot.
Saw her recently in jeepers creepers (she does these roles a lot now, just appears for a couple of minutes), but of course you have howling, critters, hills have eyes, halloween others?

also Udo Kier is also one not afraid of cashing a paycheck for halloween, frankenstein, dracula, bloodrayne, puppetmaster others?
Actually speaking of dee wallace theres another grand ol' woman of horror who is the same but can't put my name on her, I wanna say Adrienne Barbeau but its not her, though adrienne has appeared in lots

though the correct answer is no doubt someone in a charles band film

Only three, and not strictly horror, but Bill Paxton has appeared in the Alien, Terminator and Predator franchises. He was also killed by all three (if the Terminator actually killed him by throwing him against the metal gate?).

However the winner could be Lance Henriksen who also appeared in all the aforementioned franchises (if you count Alien Vs Predator as part of the Predator franchise). He also appeared in Scream, Hellraiser, House, Pumpkinhead and Piranha.

Has anyone said Bela Lugosi yet? I am probably missing someone's post, so, sorry about that. If so, I will just reiterate that he was in Dracula, of course, and also Son of Frankenstein, The Wolf Man, Frankenstein Meets the Wolf Man, etc. You could absolutely say that he was in the Dracula, Frankenstein, and Wolf Man franchises. He was also in at least one movie with zombies... zombie movies are more of a sub-genre than a franchise, but worth a mention. He was also in more than one Edgar Allen Poe-themed movie. Those aren't QUITE a franchise, but pretty close... I feel like there should be some name for whatever EAP movies are, collectively.

This guy has worked on a few
https://www.imdb.com/name/nm0313608/
reanimator, dentist, children of the corn, silent night deadly night, curse, predator, jack frost, nightmare on elm street, poltergeist
man I've rated ~90% of the films hes worked on

Good list. Not an actor in these franchises though. Crew members in the most horror franchises could be a whole separate thread.

Tony Todd: Candyman, Wishmaster, Final Destination, Hatchet, Tales from the Hood. Also the Dead franchise if you count Savini's NotLD remake.

Lin Shaye? Amityville, NoES, Critters, 2001 Maniacs (it had a sequel, does that make it a franchise?), Ouija, The Grudge, and Insidious. https://en.wikipedia.org/wiki/Lin_Shaye
