Celebrities in your T2k-Universe

[Olefin]

Take a look at World War Z for how such things could be handled - they mentioned a lot of celebrities there but not by name to avoid getting into legal issues

another way would be having them show up before they were celebrities - i.e. look at how many future Hollywood stars served in WWII (Lee Marvin and Walter Matthau come to mind right off the bat) - same here could happen

Or you have stars trying to serve their country like Jimmy Stewart and Clark Gable did - i.e. you see an F-15 go down after an aerial battle a la Red Dawn overhead and you get to the pilot who ejected to find out that its John Travolta (who is a qualified jet pilot) or you run across a squad of soldiers in Poland led by Matt Damon or Tom Hanks who had been thru the mini-boot camp for Private Ryan and joined up after the US got nuked in late 97 for real.
