What actors and actresses appeared in Paydirt - 1981?

It seems you might be mistaken about the movie title. There is no movie called "Paydirt" released in 1981. There are, however, several movies with similar titles, like "Pay Dirt" (2011) or "Pay Dirt" (1994), but those weren't released in 1981.

Could you please double-check the movie title and year of release?
