Harrison Ford was a good actor before 1998, but Cary Grant could act circles around him.
I will have to google to find the actual guy mentioned.
And how well the guy could act is and was beside the point, the point was that if you are supposed to play a bellhop, nobody should look at your performance and say “what a star!”, they should say “what a bellhop!”.
LOOKED IT UP. Famous old actor star was Tony Curtis (yonder lies the castle of my fadder) and it was Harrison Ford who was the bellhop! Tony Curtis played a grocery clerk.

One studio executive apparently told Ford that he was delivering the lines he was given, and was well-suited to portraying a bellhop or a waiter, but that he lacked star quality.
“Check out Tony Curtis in HIS first role,” the exec said. “He's a grocery clerk but you KNOW he's a movie star.”
“I thought the point was you were supposed to think he was a grocery clerk”, countered Ford, quite reasonably.
