Eric Laneuville, who played orderly Luther Hawkins on "St.
Elsewhere" -- and went on to direct several of that show`s more
memorable episodes -- has directed one episode of "ER" as well,
"Summer Run" . He also appeared in a brief cameo as an unnamed
character in "Do One, Teach One, Kill One" . (It`s also worth
noting that on "St. Elsewhere", Eric`s character later received
additional training, first as a paramedic and later as a physician
assistant [PA], which is what Jeanie Boulet is on "ER".)
