Andrew Tudor ( Genre Theory, 1974 ) and Science fiction genre conventions

Chicken and Egg' Dilemma Commonly recognised formal elements and common features of a specific genre need to be identified.
Genre conventions: SCI-FI:
Colors: Silver because many things such as moon boots and helmets are silver, Shades of blue to represent out of space and milky ways etc, neon colors for stars and planets and bright things you'd find in space, bright flash colors again for stars shooting stars etc.
Costumes: Puffy clothing as out of space you'd imagine to be cold as there would be nothing to heat it unless your near the sun and you'd need puffy clothing for protection, big white space suits, moon boots, uniforms for on board spaceships like star trek you find they are all wearing uniform.
Sounds: The sounds that you would find would be quite loud and explosive such as meteors and comets smashing into one another. The roars of shooting stars flying about. Other spaceships in outer space could be inflicting damage on other ships resulting in loud crashing sounds. In a SCI-FI film you would hear the noises and blasts of fire coming out of the back of spaceships as the soar through out of space.
Lighting: The lighting in the scene would be quite bright as it is outer space, you would have stars and galaxies dotted around all over the place and it would light up everywhere. Planets would be bright and flashes of green and blue all over the dark blue sky would make everything seem bright.
Props: The props you would get in a science fiction film would be very weird, you could have weapons for if its a fighting film like in star wars and star trek they would use lasers and guns as weapons. You would also have a lot of equipment for when astronauts are flying around space such as cords to keep them attached to the spacecraft. You would also have props like steering for the spacecraft and buttons to control what it is doing.
