Review of “A Trip to Mars” (1910)
Seen in 2022.
A scientist discovers “reverse gravity”, gently levitating a few items until he accidentally reverses gravity upon himself and lands among giants on Mars. One of them blows on him and he flies straight back to his laboratory.
Good monster makeup, and I like the twist ending: by dropping an experimental subject, possibly in an effort to dispose of it, the scientist somehow attaches its effect to the whole building or to the Earth. This is similar to something I came up with 103 years later in a TRPG campaign (1866).
