Kommissar X – Drei gelbe Katzen is a 1966 Eurospy film written and co-directed by Rudolf Zehetgruber and Gianfranco Parolini. Filmed in Ceylon, it stars Tony Kendall, Brad Harris and Dan Vadis with Harris and Vadis doing their own stuntwork. It is the second of seven films, loosely based on the 1961 Kommissar X #73 detective novel from the Pabel Moewig publishing house, though the original novel was set in Burma.
