So this service will provide prepped actors for your wedding, baptism, bar mitzvah, funeral, whatever, and then superimpose the celebrity/ies of your choice in the event video (subject to licensing, of course).

Also available for corporate endorsements (for a much higher fee, naturally).

And for the vain, we can make the bride and/or groom and/or various relatives look younger, thinner, blonder, whatever. Provided they're prepared to swear their undying bliss covered in that green goo.
