Casablanca - S2-E6
Continuity mistake: When the chief stops Maxwell from beating the cab driver, he holds back Maxwell's arm by the very prominent cuff. After the following cut he holds it by the sleeve (and no sign of the cuff). (00:05:50)
Character mistake: Maxwell translates his famous line "And loving it' into the German 'Und damit gefreut'. Agent 99 who claims to speak German fluently confirms it. This translation is both far away from the meaning and doesn't make any sense at all. The right translation is 'Und liebe es'. (00:09:50)
