But trailers are designed to maximise the hype, and presumably this was the best they could do in terms of crowd pleasing sound bites even after all the delays.
Well I can’t speak for what bits they used, as I haven’t seen the trailer. But maybe they just didn’t choose the moments based on where Alden looks/sounds the most like Harrison Ford. Or maybe Alden just decided not to do a Harrison Ford impression. Doesn’t mean it’s not a good performance that evokes the character. You can’t judge this sort of thing based on little bits, whether they showcase the best or the worst of the overall performance.
