NUMB3RS is an American television show produced by brothers Ridley and Tony Scott. The show focuses equally on the relationships between FBI Special Agent Don Eppes (Rob Morrow) and his mathematical genius brother, Charlie Eppes (David Krumholtz), who helps Don solve crimes for the FBI and their father, Alan Eppes (Judd Hirsch). A typical episode begins with a crime, which is subsequently investigated by a team of FBI agents led by Don and mathematically described by Charlie, with the help of Larry Fleinhardt (Peter MacNicol) and/or Amita Ramanujan (Navi Rawat). The insights provided by Charlie's mathematics are always in some way crucial to solving the crime.
