"The aquarium in Dr No (1962) was fake. To create it, the production team projected some stock footage of fish onto a screen. However, they only had footage of small fish, so they maximised it. In-universe, the villain explains that the glass of his aquarium has a “magnifying effect”."

"In Gravity (2013), as Kowalski flies very close to the camera, astronauts holding a movie camera and boom mic appear to be reflected in his helmet visor. This is an in-joke by the movie’s director, Alfonso Cuarón. The ‘reflections’ were added with CGI to make it look like the scene was actually filmed in space."
"In Blade:Trinity, Wesley Snipes had difficulties with the production team and at one point was even unwilling to open his eyes for the camera. Leading to this morgue scene where they had to CGI open eyes for him."

"For the first Star Wars movie, Star Wars: Episode IV – A New Hope (1977), our immediately recognizable lightsaber sound was discovered by mistake. While carrying a tape recorder with a broken mic cable where the shielding had come off, the sound was recorded as someone walked by a television. The sound is the electrical feedback from the television’s tube."
"In Captain Marvel (2019), when Monica Rambeau is changing the color of Carol Danvers’ suit, she first chooses a combination of red and gold, which are the same colors as DC’s Shazam, who was previously known as Captain Marvel."
"In 2001: A Space Odyssey (1968), director Stanley Kubrick made a floating pen using a plexiglass in which he taped the pen with a double-face tape. For 1968, it was something impressive to do without any special effect."

"In Blade Runner (1982), Ridley Scott and Jordan Cronenweth achieved the famous ‘shining eyes’ effect by using a technique invented by ‘Fritz Lang’ known as the ‘Schüfftan Process’: Light is bounced into the actors’ eyes off a piece of half-mirrored glass mounted at a 45-degree angle to the camera."
"In Alien: Resurrection (1997), Sigourney Weaver practiced for two weeks for the basketball scene and made the shot in one take. No camera tricks or CGI were used in the shot."
"In Scott Pilgrim vs. the World (2010), the scene where Scott throws a parcel over his shoulder into a bin is real. In a film with so much CGI and SFX, director Edgar Wright wanted the throw to be real for the authenticity. It took him 33 takes."
"Have you ever wondered how the shadow of the ark was made in Raiders of the Lost Ark (1981)? It makes you laugh how such a simple thing leads to the final climax with some of the best visual effects ever made."
