Comedy films aim to entertain audiences through humor and amusement. They often exaggerate real-life situations and characteristics for comedic effect. A comedy film trailer typically includes humor, sarcasm, awkward characters, shocking moments that audiences find funny, and characters in situations where they feel out of place. While comedy films don't require advanced editing or special effects, writing a genuinely funny comedy script is challenging without experience in the comedy genre, and casting the right comic actors is also important.
