“Unbelievable!!!!!” is a tribute and spoof of the low-budget sci-fi films from the 1950s and 1960s. The film features deliberately awkward and stiff dialogue, along with intentionally rudimentary special effects. The sets, costumes, and props are designed to appear improvised and low-quality. Despite this, the storyline is robust and drives the characters forward with a sense of earnestness, as if conveying a significant message. The screenplay is crafted by Steven L. Fawcette.
