When “Inside Out” hits theaters this Friday, the brightly hued Pixar film will be the studio’s 15th feature film since “Toy Story” came out 20 years ago in 1995. From toys to monsters, under the sea in “Finding Nemo” or in the clouds of “Up,” Pixar has helped redefine what it means to be an animated film. With “Inside Out,” Pixar will dive into a new world -- our minds -- in an attempt to explain our personalities and emotions.

Ahead of the film's release on June 19, check out our ranking of Pixar's films:

1. “Toy Story 3”
Perfectly coinciding with a generation of kids who grew up watching “Toy Story,” the moving on storyline hit at a personal level for parents and grown-up kids alike, while a villainous strawberry-scented teddy bear scared the young ones not attuned to the movie’s emotional core.  

2. “Up”
Containing probably the eight saddest minutes of an animated movie for kids, the wordless montage about the passing of life in “Up” is hardly a forgettable one. The ensuing tale about recapturing the spirit of adventure could easy thrill kids of all ages.  

3. “Toy Story 2”
If you were a kid when you first watched “Toy Story,” there was a chance you would be racked with guilt watching the abandoned toy plot of “Toy Story 2,” after only just dropping off a box of old playthings for donation.

4. “WALL-E”
Nearly silent and laced with an environmental message, this oddball Pixar movie about a rundown robot and a sleek new model looking to save the human race proved to be very effective, if a little trying for wee ones.

5. “Finding Nemo”
Highly quotable and immersive, this deep-blue adventure about a father-son pair of clown fishes, played well with its Aussie surroundings and cast of wacky characters for a memorable chapter in Pixar’s history.

6. “Ratatouille”
A rat in Paris with ambitions to become a cook, a clumsy kitchen boy who’s the heir apparent of a famous chef and a willowy critic with the power to shut their operation down. Director Brad Bird explored yet another underground world just waiting to be reimagined thanks to the help of a dedicated protagonist Remy (Patton Oswalt) and his unlikely co-conspirator Linguini (Lou Romano).

7. “Brave”
It wasn’t until almost two decades of Pixar movies in 2012, that the studio committed one of their projects to star a female lead. Merida (Kelly Macdonald) is a Scottish princess desperate for independence from her parents and potential suitors, making this supernatural mother-daughter tale a surprising relatable teenage story.

8. “Toy Story”
The “Story” that started it all in 1995 was an immediate success for computerized animation and introduced the world to Woody (Tom Hanks) and Buzz Lightyear (Tim Allen), both now seemingly intrinsic to the Disney name.

9. “The Incredibles”
Before the “X-Men” franchise went back in time to figure out how mutants dealt with ‘60s society, the stylized charmer “The Incredibles” followed a family of superheroes forced into retirement until a new foe arose to wipe all superheroes out.

10. “Monsters, Inc.”
Creatively building a monster world that ran on the screams of children, “The Odd Couple” pair of James P. “Sulley” Sullivan (John Goodman) and Mike Wazowski (Billy Crystal) spoofed both workplace conventions and buddy comedies.

11. “A Bug’s Life”
The studio’s first movie post-“Toy Story” success lacks a bit of the Pixar pathos, but was a creative reimagining of another microcosm life invisible to us human observers.

12. “Cars”
An ode to the small town, off road life, a hot shot racer voiced by Owen Wilson gets a humbling lesson on the priorities of life in this popular Pixar film.

13. “Monsters University”
Another cute, but harmless entry in the Pixar cannon, “Monsters University” reteamed the beloved characters voiced by Goodman and Crystal as college students, but ultimately didn’t bring the depth of its original film.

14. “Cars 2”
Lacking the emotional engine driving the original, “Cars 2” didn’t quite hit it out of the ballpark with critics like other Pixar movies. And although the “Cars” spin-off “Planes” has a lower-key fanbase, another “Cars” sequel is currently in the works at the studio.

“Inside Out” opens in theaters June 19. After looking back at the previous 14 movies and 20 years of the Pixar cannon, what are some of your favorites? Assuming they can’t all be your top films, where do you think the new “Inside Out” will land? Be sure to sound off in the comments below!
