Idea: Recruit up and coming young actors to donate sperm / eggs / DNA to a cryobank. Pay for the rights to reproduce as many gametes as desired. Then resell the sperm / eggs to parents, once the actor has become famous. Alternatively, maybe recruit stars of yesteryear? Might also work for athletes, musicians, artists, scientists.
