Audiences today expect authenticity, and casting decisions are closely scrutinized. This has led to the phenomenon known as fan casting, where fans express their preferences for specific actors to play certain roles long before casting decisions are made. Social media has amplified this phenomenon, giving fans a platform to voice their opinions and influence casting choices. This democratization of the casting process can be both beneficial and challenging, as filmmakers must balance artistic vision with audience expectations.

Turning is a machining process where a cutting tool removes material from the outer surface of a rotating workpiece. This is typically performed on a lathe, where the workpiece is held securely while the cutting tool moves linearly or radially. Turning is primarily used to create cylindrical parts, such as shafts, pins, and bolts. Variations of turning, including facing (creating flat surfaces on the ends of parts) and taper turning (producing conical shapes), are also common.
