Victor Laszlo is the Czechoslovakian underground leader in "Casablanca".
Both Leonard Nimoy and Anne Francis guested on the same episode of Columbo (1971): A Stitch in Crime (1973). Nimoy played a murderous heart surgeon and Anne Francis played his first victim.
The ten million dollars offered to Victor Laszlo (James Patterson) would be the equivalent of about $74,400,000.00 in the year 2021.
Aside from the apartment briefing and final scene, Leonard Nimoy is only in character as Laszlo's double in the "false" apartment scenes.
