Still trying to get the taste of that SNL with Robert DeNiro out of your mouth? Why are you putting TV shows in your mouth, anyhow? Just replace that memory with a happy one, like, oh, say, DeNiro and Charles Grodin in Midnight Run. See! I just turned your frowny face and flipped it and reversed it, because you're looking into an imaginary mirror and smiling.
Now watch this video in which Charles Grodin tells you everything you need to know about acting, based on all of the acting classes Grodin has experienced. It reminds me of the debates you hear among comedians about comedy classes — and also about the debates you hear journalists make about journalism school. Just do the work. Put in the work. Oh, and thank SNL's Abby Elliott for pointing me to this to show it to you.
Everything: Full circle. Roll it!
