John Waters made movies with his friends since his first film, Hag in a Black Leather Jacket. The group of people he featured as actors came to be known as the Dreamlanders. David Lochary was in every film after Hag and up to Female Trouble.
In Pink Flamingos he played Raymond Marble - one half of the villainous wannabe filth duo that sought to dethrone Divine as the "Filthiest Person Alive" (Mink Stole, the other). To dye his hair blue for the role he bleached it and opened up blue markers, using the ink for color.
In his personal life he was a best friend to Divine and his original makeup artist.
Sadly, Lochary died at the too young age of 32.
