Now that I've got your attention, yes, Carlos Bernard, who played Tony Almeida on 24, will be appearing in the upcoming back half of season 3 of Burn Notice.
Details on whether he'll be a client or a nemesis of Michael Westen, played by Jeffrey Donovan, has yet to be disclosed.
Carlos already filmed his role and now, all we have to do is wait until Burn Notice returns from its midseason break. Grr.
I know you can't cross franchises, but wouldn't that be sweet?
