Not really in his prime. You are conflating popular and mainstream. I’m old enough to have watched delirious and raw when it was released on video. Eddie was popular but the mainstream didn’t embrace him until the dr Doolittle years. That’s well beyond his prime.

Popular is literally a synonym for mainstream, they aren't being conflated. He went mainstream before Raw with Beverly Hills Cop, by the time Raw came out he was already a star. Doolittle was long after his prime, and long long after he went mainstream.
