My wife watched this together some years ago ... it's a particular favorite of hers. This time, we enjoyed a 4K Blu-ray ... it looked great. I haven't changed my mind about the movie, so here's a mostly cut-and-paste from what I wrote in 2016:
A perfect title for a movie that excels as escapist entertainment without offering anything more.
I feel like The Great Escape is remembered fondly by those who saw it on its release. It did well at the box office, and we watched it again mostly because both my wife and I recalled liking it long ago. It is very straightforward, constructed in an easy-to-understand manner, with an effective slow build until the actual escape (the film is too long at almost three hours, but once it gets there, it delivers). Whatever liberties are taken with the actual events, the downbeat ending is very much in tune with those events, and perhaps give The Great Escape slightly more resonance than other blockbusters. But it is a stretch to make too much of that resonance.
Bruce Eder thinks highly of The Great Escape:
John Sturges' The Great Escape could easily be the most under-appreciated movie of its genre and decade ... Beneath the fact-based heroics, the humor of many of the portrayals and Elmer Bernstein's rich, rousing score lay the elements of a classic tragedy. While ordinary viewers responded to the driving dramatic forces among the characters ... critics and scholars viewed the movie as an artless, empty blockbuster. They were looking for self-conscious subtlety and obvious artistic touches in a story that required only a straightforward, unpretentious telling. The Great Escape expresses its depth and drama through action rather than ponderous dialogue, and in that sense, was probably too true to its subject for its own good, at least in terms of achieving critical respect.
Eder’s description of the film is accurate, but he concocts a straw-man critic that I don’t think exists. The Great Escape is far from artless, but who exactly needed “self-conscious subtlety and obvious artistic touches”? Movies that emphasize action are not rejected by critics, who, as far as I know, hate “ponderous dialogue” as much as the next person. The Great Escape is what it wants and needs to be, and audiences respond to that. There is no need to “elevate” it beyond its clear virtues.
The “based on a true story” angle is about as close to real as it ever is. There was an escape. Americans were not an important part of that escape, but for box-office purposes, Steve McQueen and James Garner were signed up and given big parts. The most iconic scene in the film, McQueen’s chase on a motorcycle, never happened. McQueen asked for a motorcycle scene because he liked to ride. That no American tried to escape on a motorcycle is irrelevant ... it’s the best scene in the movie, the one people remember fifty years later.
The Great Escape is a fine adventure that holds your attention for nearly three hours. That is good enough. #866 on the They Shoot Pictures, Don’t They list of the top 1000 films of all time.
