After Sid (John Leguizamo) pilfers some dinosaur eggs, Manny (Ray Romano), Diego (Denis Leary) and the rest of their prehistoric pals enter a mysterious, underground world to rescue the hapless sloth.

Denis Leary is returning to the movies ... playing the scruffy sabertooth Diego, and appeared as Captain Stacy in the Andrew Garfield Spider-Man movies released in the mid-2010s.
