Over the years, the story transitioned from a buddy comedy featuring the characters of Grug and Guy to a family-themed tale with a host of major characters.

Chunky the "Macawnivore" started out as a bit of a joke in the art department. Artist Leighton Hickman was bored with the drab colors intended for creatures in the desert scenes, and painted the saber-tooth tiger with bright "parrot" colors. The filmmakers liked the look for the "Macawnivore" so much that it made it to the final film.

In March 2007, Chris Sanders (Beauty and the Beast (1991), The Lion King (1994), Mulan (1998), Lilo & Stitch (2002)) joined DreamWorks to direct the film, with intentions to significantly rewrite the script. In September 2008, it was reported that Sanders took over How to Train Your Dragon (2010) putting The Croods on hold, and thus postponing its original schedule for a year to a then planned March 2012. The film's final title, The Croods (2013), was revealed in May 2009, along with new co-director, Kirk De Micco. In March 2011, the film got another delay, being pushed back a year to March 1, 2013, and finally settled at March 22.

During the second scene with the Punch Monkeys, when Guy hands one a banana, the monkey's fingers pass through the banana when he squeezes it.

When the family re-unites in the final act, the Trip Gerbil (one of the rescued pets) is noticeably absent as they stand in awe of their new home while the other pets are still in scene.

When the family goes out hunting for breakfast in "breakfast formation", Eep starts out on her fathers left side but is on his right side in the next shot. If it's a formation, you stay in position.

Eep: [Grug hugs Eep] This is good... what do you call this?

Guy: Okay, open them. I call them shoes.

Grug: [Smears mud on Thunk's face] Paintings are so passe. I call this a snapshot.
