Continuity mistake: When Rockford is with Agent Kleinhoff on the tarmac, the airplane Rockford boards has N-number N664CL, but the airplane that takes off has many more windows and a Canadian flag (it's not the 70's Air Canada logo) on its tail; then the plane in midair has N-number N953GA. Mid flight there are more discrepancies in the airplane's configuration. Finally, the airplane that lands has the original tail number N664CL. (00:06:35)
Continuity mistake: When Rockford first sees Christine during her photo session, in the wide shot Christine is brought a glass of wine which she holds in her right hand while the white flower is in her left hand; then the wine glass and flower switch hands in the next closeup. This change continues to occur in following shots. (00:18:50)
