Unit 4 Pre Production Learning Aim A Three key pre-production roles and tasks are discussed for scenes from the Buffy the Vampire Slayer episode "The I In Team": ideas generation and writing, location selection and set design, and special effects or visual effects planning. Pre-production for a scene set in Xander's basement involved planning from the writing team and selecting recurring props and costumes. Another scene set in the woods required locating a filming location, procuring permits and equipment, and choreographing a fight sequence. Pre-production ensures scenes are properly planned, permitted, and can be shot to fit the creative vision.
