"I was lucky. Emma Stone had remained good friends with Bill Murray since “Zombieland.” It was Emma who first reached out and sent him a text. Did he want to join us in the fall, in Hawaii? Murray wrote back: “You. Hawaii. Crowe. Sounds interesting.” We both jumped up and down for a very long time, and then tried not to get too excited. Of course the excitement only built. I sent him a script, a little music and some books about the world of the character. One night Bill Murray called back, and I missed the call. No return number. And then there was silence. My friends tortured me mercilessly for missing Bill Murray’s call. (I picked up the phone hopefully, on the first ring, for weeks. Nothing.) Then came a text from Bill. And he’d sent one to Emma too. He had enjoyed some of the music I’d sent. I texted back immediately, and also asked a question about the young actor we were about to hire, Jaeden Lieberher. (Jaeden was also acting with Murray in “St. Vincent.”) Murray was enthusiastic in his praise for Jaeden. We hired Jaeden. Hiring Murray would not be so easy. We attempted to engage with his lawyer, but those discussions faltered without official word that Murray was in fact really interested. Sony officials warned us to start looking elsewhere — it didn’t look good. And then late one night came another text, not from Bill… but from young Jaeden. It read: “I just saw Bill at the wrap party. He told me to tell you, ‘Don’t listen to the suits. I’m coming to Hawaii. Aloha, Bill.’” And that’s how we found out he was going to be in the movie. He told us through his 10 year-old co-star, who I immediately nicknamed “Bill Murray’s Agent.”"
