Harrison Ford is not very good in it—perhaps not a great actor generally. His pretending to be a nerd/fan in Zhora's dressing room is too cringey to watch it's so bad… I feel like I'm watching Mickey Rooney playing Mr. Yunioshi in Breakfast at Tiffany's.
And the actor that played Leon (Brion James) is also difficult to watch (he was a distraction in The Fifth Element as well).
My only complaints though.
