Conrad and Jonah watch a scene from an old movie in which his father Gene stars as actor. This is a scene from an actual movie titled Hello Again (1987), starring Shelley Long and Gabriel Byrne.
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.
Due to the terrorist attacks in France, the title for the local release was changed to 'Back Home'
First Norwegian film since 1979 to be featured at Cannes Film Festival in the main competition.
