Danny DeVito (Bob)
In his last movie with Disney, Tim Burton’s live action take on Dumbo, Danny DeVito played the guy who ran the circus, but in The One and Only Ivan, he does not even play one of the circus acts. The beloved, 75-year-old Golden Globe winner is the voice of Bob, a stray dog who makes himself Ivan’s roommate and, in some cases, his “hype man,” so to speak. Not only is this the It’s Always Sunny In Philadelphia star’s second time playing a dog after 1993’s Look Who’s Talking Now, but voice acting has practically become one of DeVito’s many specialties, bringing his signature growl to the an alien theme park owner threatening the Looney Tunes in Space Jam, Philoctetes in Hercules, the title role of 2012 Dr. Seuss adaptation The Lorax, and, more recently, a yeti named Dorgle in Smallfoot.
