The Big T.N.T. Show was aimed at the teenage demographic and featured 3,000 teenagers in the audience.^[3] "T.N.T." was an acronym for Tune 'n' Talent.^[2] The film was a follow-up to the T.A.M.I. Show, which was released a year prior. "T.A.M.I." was an acronym for "Teenage Awards Music International."^[2]

The concert was shot on videotape and transferred to 35-millimeter film.^[4][5] Director Larry Peerce used four television cameras to record the performances. Record producer Phil Spector was the producer and musical director.^[1]

According to executive producer Henry G. Saperstein, 140 minutes of footage was shot,^[1] but the film was cut down to 90 minutes for the theatrical release.^[6] Each of the acts performed their set three times.^[1]

UPI Hollywood columnist Vernon Scott wrote that the "film is aimed solely at kids who buy recoding of the performers in the cast. It's a musical orgy for pubescent swingers."^[2]
