Star Wars director George Lucas voiced his concerns about The Phantom Menace ahead of the film’s release in 1999.
Rian Johnson’s Star Wars: The Last Jedi is in cinemas now and has officially crossed the $1bn (£737.7m) mark worldwide.
The footage can be seen as part of the hour-long documentary ‘The Beginning: Making Episode I’ featured on the film’s DVD extras.
In behind-the-scenes footage highlighted by The Hollywood Reporter, Lucas can be seen unimpressed with a rough cut of the film, seemingly unsure of how to rectify the finished product.
