"Biggles: Adventures In Time"
Plenty of 80's cheese with a time travel twist. An ad executive in the 80's changes places with a World War 1 pilot named Biggles, whenever one or the other is in mortal danger. Which means he's going to do an awful lot of traveling with Biggles and his team of stalwart military movie stereotypes attempting to find and destroy a new, German secret weapon. During their adventures, Biggles travels to the 80's where he and the ad exec steal a helicopter to aid in destroying the German weapon...which somehow Biggles is miraculously able to fly. Special note: this film was one of Peter Cushing's last film roles before passing away.

This one looks quite fun for the Riff treatment.
