Richard Wilson (extra)
From Tardis Wiki, the free Doctor Who reference
Richard Wilson had an uncredited role as one of the schoolchildren in "The Pilot Episode." His other film and television roles, if any, are unknown. He is not to be confused with the Richard Wilson who appeared as Dr. Constantine in DW: The Empty Child and DW: The Doctor Dances, as that Richard Wilson was 27 at the time "The Pilot Episode" was produced and so was probably too old to portray a young student.
