Celebrate the 40th anniversary of "Monty Python and the Holy Grail" with this 14-minute video of previously unseen animations by Terry Gilliam, who also explains the inspiration behind his work.

The animations are narrated by Terry Gilliam, who worked on the animations. There’s even some Neil Innes music that was cut from the film, as well. It’s all quite funny, if Monty Python is ...

The video has surfaced ahead of the theatrical re-release of the Monty Python and the Holy Grail, 40 years after it originally came out. It is also being released on Blu-ray and DVD on October 27.

Included in this Blu-Ray box set are a handful of new tidbits, the most intriguing of all being 14-minutes of lost animation footage with a commentary by Monty Python alum Terry Gilliam.

Included in the material is 14 minutes of cut animations, all narrated by director Terry Gilliam. Monty Python has also graciously posted the sequence on YouTube for your enjoyment.
