Andrew McCarthy was still a teenager when he acted in his first film and became a member of what’s called the Brat Pack. That’s the group of actors including Demi Moore and Molly Ringwald who starred in 1980s films like Pretty in Pink and St. Elmo’s Fire. There were a few bumps along the road like drinking too much alcohol and taking drugs before McCarthy became a travel writer. McCarthy also directs episodes of TV series like Orange is the New Black. And he walked 500 miles across Spain with his teenage son, an adventure he writes about in a new book called Walking with Sam. “Now What?” is produced with the help of Steve Zimmer, Lucy Little and Cameryn Yarber. Audio production is by Nick Ciavatta.
