I would tend to disagree. The Marx Brothers were the best.
Modern Times was the greatest movie ever made imho, and his other feature-lengths were amazing, too.
On the other hand, the Marx Brothers so smoothly complemented each other that the four of them were greater than the sum of each one’s respective roles. My favorite line from Chico: “You no-a-fool-me. There aint-a no Sanity Clause.” Harpo: Answering the phone with a set of horns that imitated speech. But Groucho was all-encompassing. Everything he said was the funniest thing he ever said.
