In general the vecchi are portrayed as selfish, and quite prone to committing any and all of the seven deadly sins (lust, sloth, greed, pride, wrath, gluttony, envy.) They also are often hypocrites, demanding acts of sacrifice and loyalty from others they would never perform themselves, save for an occasional and usually sudden change of heart in the final act to allow a happy ending. (Felix)
The job of the vecchi was to completely sabotage the innamorati’s happiness. The costumes and masks the vecchi wore were easily identifiable because their masks were dark and unique and their costumes were high-end in comparison to the rest of the cast.
About 20 minutes into the film The Rocky Horror Picture Show, an elevator door opens and the actor Tim Curry steps out. His face is heavily mascaraed, the portrait of a commedia dell'arte drag queen. Everything below that striking visage is covered in a magnificent cape. He struts out, to the beat of a Stonesian guitar riff, and a few moments later he turns and rips off the cape: We can see he sports a glistening string of giant pearls and, not least, a silver-spangled ensemble of women's lingerie.
