The movie 'Escape from Alcatraz' is indeed based on true events. It tells the story of prisoners' efforts to break out of the notorious prison, although some elements might be dramatized for cinematic effect.
One such film could be '127 Hours'. It's based on the true story of Aron Ralston. He got trapped while canyoneering in Utah. The movie shows his struggle for survival in a very real and intense way.
The fact that it's based on a true story makes it more relatable. For example, in '127 Hours', we know that a real person actually endured that. It gives a sense of authenticity that fictional stories may lack.
Well, 'No Escape' is purely fictional. The plot and characters were made up by the writers to captivate the audience and offer an exciting viewing experience.
