Jared asked, “Well, what am I talking about?” And I said, “Well, tell the story about trying to ride a cow.” And he’s like, “What?” I was like, “Just go with it. Just improvise a story about riding your neighbor’s cow.” And, God love him, Jared just went in there and started talking about the neighbor’s cow. We had to shoot it a few times because he kept accidentally saying that the cow was owned by Colin Farrell, instead of Colleen Foley, which was the name we came up with. So, they were laughing and laughing. But when they finally got a take that worked, it was so beautiful to me. Just watching Jared’s performance but also watching Liam Garrigan’s performance, which is not sentimental in the least. In all of these scenes, the performances are so wonderful and that scene in particular, because there was an element of not quite being sure how we were going to end the dialogue. That meant that the actors got to step in and improvise with us. It was wonderful.
