Judge Reinhold's going to miss out on more exposure and a payday -- he's cancelled his appearance at Paradise City Comic Con this weekend.
Paradise City organizers tell TMZ ... Judge was scheduled to be in Fort Lauderdale Thursday until Sunday to meet fans of his movies -- "Beverly Hills Cop," "Ruthless People," "Fast Times at Ridgemont High," etc. -- but they are no longer expecting him.
We're told the cancellation is due to his arrest at Dallas Love Field airport. Too bad for Judge ... he could have hauled in some decent cash -- $40 a pop for professional photo ops, plus more for autographs and selfies.
Organizers say he's welcome back next year.
