Howard Barnum passes along this link to a home video of the 5th Solvay conference held in 1927. It was at this conference that Heisenberg and Born delivered a paper in which they said
We regard quantum mechanics as a complete theory for which the fundamental physical and mathematical hypotheses are no longer susceptible of modification.
17 of the 29 participants in this Solvay conference were current or future Nobel prize winners.
The home video gives evidence that physicists have alway been jovial joking hams for the camera.
