Bug!

 

BUG-1975-In a small town an earthquake unleashes cockroach like bugs that can start fires. A bug doc James Parmiter (Bradford Dillman) and student Gerald Methbaum (Richard Gilliland) investigate.They get help from a chemist Mark Ross (Alan Fudge). Most of the invaders die from air pressure but Parmiter keeps one specimen alive. When she wife (Joanna Miles) is killed she goes a little crazy and breeds the remaining bug with everyday roaches and creates a fast breeding bunch of intelligent flying roaches (worse than before). They kill Ross' wife (Patty McCormack) and terrorize Parmiter and set him on fire. He falls into a fissure and the flying bugs seem to follow him. Also with Jesse Vint and Frederic Brown. 

BUG's screenplay was co-written by the legendary William Castle (who also produced) and Thomas Page who wrote the novel the movie is based on. French born director Jeannot Szwarc mostly worked on TV series (NIGHT GALLERY; KOJAK) and made for TV movies. BUG was a rare theatrical release but in the early '80's he made several high profile feature films (JAWS 2; SOMEWHERE IN TIME; SUPERGIRL; SANTA CLAUS: THE MOVIE). BUG is genuinely creepy and the story is a little more unusual than most.
