Top Ten Movie Star Duos and Teams that Played in Multiple Films Together
Any two or more actors/actresses that played in multiple films together count. Duos or teams. It's not necessary to add any comments below an item, but it might make it easier for some to recognize them quicker if you do. Any portion of an actor team counts as long as it's two or more.
Laurel and Hardy. They have starred in 27 full length feature films together. That's not even counting the whopping 79 shorts (45 sound and 34 silent) that they collaborated on.

Abbott and Costello. Were we keeping score (we're not), this duo had become very familiar with one another.They have appeared in 36 films together.

Martin and Lewis. A collaboration that lasted exactly 10 years to the day, on both stage and screen. In the 8 years that included their films, Martin and Lewis made 17 films together, although their last collaboration was very short cameo appearances in a dream sequence.
Hart and"The Rock" have appeared in 5 films together.

Khan and Dixit. The Bollywood heartthrobs of the 1990's and early 2000's. At least 4 films together that I'm aware of.
Clooney and Pitt have at least 4 movies off the top of my head: The Oceans 11,12 &13 movies, and Burn After Reading.

McKellen, Mortensen and Wood starred in The Lord Of The Rings Trilogy together. A great many more actors/actresses shared in this epic film trilogy.
I would be less inclined to count series given that they obviously will have some of the same actors but of course they did great honestly I'm realizing I have no idea who my favorite Lord of The Rings character is despite how much I love LOTR.

Bogie and Bacall. They made 4 films together and of course are one of the most famous couples in the history of Hollywood.

Garfield and Stone have at least 2 movies together, The Amazing Spider Man series.
Avalon and Funicello are credited with having done 5 movies together, all in the Beach Party series.
Starred together in the original X-Men trilogy and reunited for Days of Future Past.
Starred together in all eight Harry Potter films.
These cats did 9 movies together. Not too shabby for a stoner comedic duo that started out putting out comedy albums. And yes, some of their films were not about weed.

Taylor and Burton did 11 films together. They are one of the UK's most famous couples
Made 8 films together. Romantic partners both on and off the screen
"Three Amigos", both "Father of the Bride" movies, and "Only Murders In the Building"
