Here is an actual scene from the movie The Wonderful World of The Brothers Grimm in full 3-strip Cinerama. This comes from this page - http://www.widescreenmuseum.com/special/cinerama.htm on Marty Hart's wonderful web site.

Below is the same scene from the Turner Classic Movies broadcast

Below from the laser disc

 

The scenes from the Turner Classic Movie broadcast and laser disc were copied from VHS tape many years ago so, the picture quality is not that good. I then copied it to a DVD-R before uploading them to the web site.

Below are more examples of scenes with the TCM broadcast on top and the laser disc below it.

Here are a couple of scenes from the prologue on the TCM broadcast

The laser disc had the sound from the prologue but no picture. 

 

 The TCM broadcast also included the overture and intermission music which the laser disc did not have.
