His first starring role came in the film Winter Follies, directed by Darren Lynn Bousman who also helmed Saw II, Saw III and Saw IV.
David was one of the eight selected for the Apprentice program at the Actor's Theatre of Louisville and was also later granted a scholarship to the British Academy of Dramatic Arts but his career prevented him from accepting straight away.
He has training in many different acting styles including Method, Meisner, Viewpoints and Suzuki. David has also had extensive improvisation training and comedy experience.
Blue performed in the premiere workshop production of Ain't No Mountain High Enough at the Mark Taper Forum. The musical was based on the works of Motown creator Berry Gordy and directed by Kenny Leon who had previously directed Sean Combs in the Broadway production of A Raisin in the Sun.
On Ugly Betty, Blue guest stars as Cliff, a photographer at Mode magazine and love interest to Wilhelmina Slater's faithful assistant, Marc St. James, played by Michael Urie.

Blue was part of the one-night celebrity performed staging of Howard Ashman's unproduced musical Dreamstuff. The musical was re-imagined by Howard's partners Marsha Malamet and Dennis Green and performed one night only at Los Angeles' Hayworth Theatre as part of the Bruno Kirby celebrity reading series, directed by his Ugly Betty co-star Michael Urie.
David starred in the show alongside Eden Espinosa, Fred Willard, Vicki Lewis and Luke MacFarlane.
