Try my formula: Never learn an actor’s name. Go to the movies and enjoy the story. Ignore all news about the actors in real life. You’d be surprised how well this works.
I try to just watch old movies, and ignore most of the horrible remakes of today.
And of course, I never really considered actors, singers or sports stars to be “heroes”, so that helps.
I watch less than eight hours of TV per week now, and I do that sporadically. That helps A WHOLE D@MN LOT!!!
