Did anyone else notice the stammer in the new Spielberg trailer? In the trailer for the new movie. Disclosure Day. One of the characters, Emily, appears to stammer. It made me stop and think — because stammering is rarely shown in big films, and when it is, it usually has a purpose. Do you think filmmakers include a character who stammers to show vulnerability? realism? intelligence behind struggle? or something deeper? As someone who stammers, seeing it included made me curious rather than uncomfortable. Interested to hear thoughts from others who stammer — did this moment stand out to you too?
