whether you stay obsessed with pop culture long enough,at some point in your life you become aware of the at least semi-artificial nature of things like talk shows, red carpet interviews, or press junkets. whether an actor is promoting a immense blockbuster,they're usually not saying what they're saying entirely off the cuff. An entire publicity team has prepared talking points, told them which topics to embrace and to avoid, or generally prepared them to hype the movie in a spoiler-free way.
