Poster began a notable career in the media industry as a writer and producer in 1991 on the film A Matter of Degrees. After this, Randall produced another two films until 1994, when he found his niche working in the music department of more than sixty TV shows and films from then on, through his most recent piece of work, "Grey Gardens" (currently in post production), all in the role of music supervisor.
In 1992, Randall Poster and a co-worker from A Matter of Degrees were nominated for an Independant Spirit Award, although they did not win.
