John Lennon (right) vs. Fohn in "How I Won the War"
A friend sent this clue below. It needs to be fleshed out more, so if anyone wants to help with the research, please contact me.
In the dark comedy "How I Won the War" with what appears to be a John Lennon double, I believe there is a significant "clue" in the plot.
In a twist of surrealism, each soldier that dies under the Lieutenant's command returns immediately after, replaced by a soldier painted to resemble a plastic army man. From Goodbody's perspective, that man is still alive. Footage shown during the death scenes of these characters is tinted a certain color for each incident (green, then pink, then red, then blue), and the dead soldier 'returns' in that color.
Those are the same colors the new Beatles are dressed in on the cover of the Sergeant Peppers album!!
