Conrad and Jonah watch in the computer a scene from an old movie where his father Gene appeared as actor. This scene is for real and it belongs to the movie Hello Again (1987), starred by Shelley Long and Gabriel Byrne, who plays Gene in this movie.
A New York reporter posted on Twitter (August, 2014) a casting call ad for this movie that he found in some places in New York. It read "Looking for a Young Jesse Eisenberg for the feature film Louder Than Bombs directed by Joachim Trier shooting in October (2013) in the NY area. Must be 6-10 years-old; Blue eyes; fair skinned/no acting experience necessary!" The ad included a young picture of Eisenberg, and an e-mail to contact for more information and to submit a recent picture. Julian Murdoch was selected for the role.
