I love this film. It's long, 3 hours, but it never drags. The actors are all good, as are their performances. If you like aircraft, adventure and just plain going fast, you'll love it.
Once you get past the sluggish start and rather irritating mannerisms and drawl, this is a wonderful film. The lead characters and actors are very likeable and the main action scenes are superb. It is also fascinating to see a view (albeit in a movie but hopefully based on some reality) of behind the scenes, particularly the trials and tests for the pilots/astronauts, the dynamic with their wives and families, and the media and political circus around the 1960s’ US rocket program. It is striking as well to see the lack of diversity in whom was even considered for the space program in the 1960s. Best seen in a couple of sittings as it is quite a long film, but really enjoyable.
