2.In Knives Out (2019), because there were several close-ups with characters who wore glasses, Matt Mania, the movie's Key Grip, created appliques to put over the lights so that the film crew wouldn't be seen in the glasses' reflections.

3.In Mission: Impossible - Fallout (2018), to get the shot of Tom Cruise's character jumping off the plane, the cinematographer also had to sky dive with him.

4.In Sh! The Octopus (1937), since VFX weren't as far along in the 1930s, the filmmakers used an optical illusion to create the effect of a woman turning into a creature before our very eyes.

In a Corridor Crew video, Niko Pueringer explained just how the effect was achieved. He said, "This is an effect that's only possible in black and white. It's quite simple actually. It's just a red and blue filter. Just like when you have like 3D glasses, and where the red side doesn't let you see the red lines and the blue side doesn't let you see the blue lines." He explained, "So, you have a red filter in front of the camera and it's filtering out any red on her. So, you have all these red marks on her face but you can't see any of that because the red filter is cutting all of it out. You transition it to a blue filter and suddenly all of those red splotches become bright and you can see all of the luminance difference."

5.In Star Wars: The Force Awakens (2015), BB-8 was controlled by a group of puppeteers wearing greenscreen suits who would literally push him around the set.

11.In Iron Man 3 (2013), during the final scene, Robert Downey Jr.'s head was actually CGIed onto a body double because, at the time, RDJ suffered an injury that halted production for six weeks.

16.And finally, in The Matrix (1999), in order to capture Keanu Reeves' iconic bullet-defying moment, 120 still-cameras were placed around him all capturing photos within milliseconds of each other. Then, those photos were stitched together to achieve that slow-motion effect.
