"Last Crusade" is always a joy to watch. At 2hr 7 mins the time just flies by, there is never a dull moment. There is a great variety of action, they manage to fit in horseback, train, car, airplane, boat, motorcycle and tank action scenes. All of these scenes are done at the very top of their class.
All the main cast work off of each other perfectly, and there is fantastic chemistry between Sean Connery and Harrison Ford as the father/son duo at the core of this film. The real predecessor to Indiana Jones is James Bond, so it makes sense that Sean Connery would play the father of Indiana Jones. But beyond stunt casting, Sean Connery's Henry Jones is a delight, and is memorable in every scene he is in.
This film also blends together action and comedy perfectly. It never clashes with the tone and always allows the serious moments to sink in. But when they do a joke, it is legitimately a very funny joke.
And how I can go without mentioning the music? John Williams delivers some of the best music of his career in this entry. The music compliments what is going on on screen so well, you could picture the scenes in your mind just through listening through the soundtrack.
Where some may prefer "Raiders of the Lost Arc" for its originality and grit, I prefer "Last Crusade" for its refining and perfecting everything the series had set up. The ending of this film is also just more satisfying and exciting than the ending of "Raiders". The Holy Grail is the best maguffin of the series, and possibly of all time. There is something inherently legendary about people questing to find the Holy Grail.
If you haven't seen this film: WATCH IT. If you have seen this film a dozen times already: go ahead and watch it again. It is always entertaining, exciting and illuminating. What a great way to END a great trilogy.
