1. ‘Mac & Me’ (1988) — Sequels That Never Happened

At the end of the 'E.T.' rip-off, er, homage 'Mac & Me ,' a family of Coke-lovin’ space-aliens drive along the highway in a pink convertible while young Mac blows a bubble which reads, “We’ll be back.” Once again, there was no sequel. You’d think that after the failure of 'Mac & Me,' Ronald McDonald (who appeared in the film as himself) would keep his distance from comedic/heart-warming alien-adventures. But you’d be wrong.  In 1999, Ronald and friends starred in 'The Wacky Adventures of Ronald McDonald: Visitors from Outer Space.'
