Doc Hopper is the main antagonist in The Muppet Movie. He was portrayed by the late Charles Durning.
He is the Southern-bred owner of the Doc Hopper's French Fried Frog Legs chain of fast food restaurants. When Hopper sees Kermit dancing, after being informed of the frog by his assistant Max, he's determined to have him as a spokesfrog, and he won't take no for an answer. Doc previously handled his own commercials, wearing a frog suit.
Doc Hopper's dream is to expand his franchise and own 1,000 restaurants. To achieve this goal, Hopper single-mindedly pursues Kermit halfway across the country in his limo, becoming the villain of the film in the process. Doc's methods become increasingly desperate (bringing about a crisis of conscience for Max), hiring mad scientist Professor Krassman to brainwash Kermit (he kidnapped Miss Piggy to lure Kermit to Krassman) and later enlisting Snake Walker Snake Walker and other thugs to kill the frog if he refuses. Doc's ambitions and ruthless determination are contrasted with Kermit's desire to spread joy and happiness to others. While Kermit's dream "becomes better the more people you share it with", encompassing a range of characters, Doc's goals are exclusionary, isolating him even from Max.
During their final standoff at an abandoned ghost town, Kermit makes a final plea to Doc Hopper, saying that all he wants is to fulfill his and his friends' dream, and that perhaps if Doc put aside his own selfish intent, he would see that he didn't want to continue his pursuit of the gang. Unfortunately, Doc ultimately decided that if Kermit wasn't going to be his spokesman, then he should die instead. Just as Doc's men prepared to finish off the Muppets, Animal plowed through the roof of Dr. Bunsen Honeydew's lab, having consumed a large number of Insta-Grow Pills. Animal then roared loudly, scaring off Doc and his men, with Max wishing the Muppets the best of luck before he too fled. After that, Doc Hopper never bothered Kermit again.
- Doc Hopper is similar to to Gaston, as they wanted someone to do what they want. Hopper wanted Kermit to be his restaurant mascot, and Gaston wanted Belle to be his wife.
