If you are looking for a definitive biography of the life of boxer James Corbett, then this is probably not the film for you. The famed boxer receives a 1940s "Hollywood-ization" of his life--making the story far more entertaining and engaging than real life. However, because the performances were so good (particularly by Errol Flynn) and the script so likable, the film's embellishments can be forgiven.
Errol Flynn plays Gay Nineties-era boxer James "Gentleman Jim" Corbett--a man who became world boxing champ in 1892. The film goes from his rather humble beginnings and follows his through his career through him winning the title match against John L. Sullivan. However, while it could have focused mostly on the matches, most are rather brief in the film (except for the final title match) and the emphasis is on Corbett's brash personality as well as his relationship with the lady played by Alexis Smith. Throughout the film, there is excellent supporting work done by a cast of wonderful supporting actors (such as the perennial supporting actor in Flynn films, Alan Hale) and the writing really helped bring these people alive.
What is particularly nice about the film is seeing the athleticism of Flynn as a boxer. While a few of the shots are of doubles, almost all the boxing scenes are of Flynn and he did a convincing job as a pugilist. This was a nice departure for Flynn, who generally played "pretty boy" roles or swashbucklers and this shows just how tough a character he was. To find out more about this, try reading a biography of him--he was quite the rough and tumble character before coming to Hollywood.
Now as for the REAL James Corbett, read on if you aren't afraid of finding out how the movie isn't accurate. First, Corbett was NOT a poor guy coming from a poor family, but was college educated and bright. Second, while he DID get Alexis Smith at the end of the film, they also divorced a few years later. Third, the wonderfully touching final scene of the film between Sullivan and Corbett was probably the best part of the film, Sullivan was a jerk and this never could have happened--in reality, Sullivan was more the egomaniac and Corbett was not the fat-headed guy they portrayed in the film--though it made for a lovely film.

This is the single worst movie I have ever seen. I cannot express how bad it is. I honestly wanted to kill myself several times through this atrocious experience just to have the pain end. I recommend instead of seeing this movie, you bathe in acid then you will at least know a fraction of the pain without all of the scars.
I had such high expectations when I read the back of the DVD case, and when in the beginning it added that Jesus was following them I was so excited... then by the end I wanted to kill myself. I mean a twenty-three minute introduction to the most annoying characters in the history of cinema... JUST PAIN! Monkeys could have done a better job editing this trash. At least they would have thrown feces and blurred some of the garbage. It would have made it better to have not seen any of the horror.
It wasn't that I didn't get the jokes, it's that they were not only not funny, they repeated themselves like twenty times. Apparently, something isn't funny unless you see it like a million times.
Do not under any circumstances see this. People have rated 'Manos the Hands of Fate' as the worlds worst movie. I have seen that too and agree that it is bad... but ALAS it is only the second worst. 'Fatty Drives the Bus' is by far worse.
This deserves all kind of harsh language, but I can't write that here so just imagine I swore a whole bunch.
