Amazon Prime Video has expanded its streaming library for September 2025, adding several new films, including a lesser-known teen comedy featuring Robert Downey Jr. that has gained a dedicated following despite flying under the radar during its initial release.
The streaming service’s latest content update brings a mix of recent releases and older titles to subscribers, with the Downey Jr. comedy standing out as a highlight among film enthusiasts. While Amazon has not released the complete list of all new additions, the inclusion of this particular teen comedy has already generated buzz on social media.
Underrated Gem Joins Streaming Lineup
The teen comedy starring Downey Jr. joins Prime Video’s catalog at a time when the actor continues to maintain his status as one of Hollywood’s most bankable stars. Though the film didn’t achieve blockbuster status during its theatrical run, it has since developed a loyal fanbase who praise its humor, performances, and writing.
Film critics have previously noted the movie’s smart dialogue and Downey Jr.’s characteristic charm, which shines through even in this earlier work. The actor, known primarily for his role as Tony Stark/Iron Man in the Marvel Cinematic Universe, has a diverse filmography that includes several comedic roles that showcase his range beyond superhero films.
September’s Expanded Content Library
Beyond the Downey Jr. comedy, Amazon’s September lineup includes:
- Several recent theatrical releases are making their streaming debut
- Classic films from various decades
- Independent productions that received critical acclaim
This content refresh comes as streaming platforms continue competing for subscribers by expanding their libraries with a mix of exclusive content and beloved classics. Amazon Prime Video has been steadily building its film offerings to compete with other major streaming services.
Streaming Competition Heats Up
The addition of these films to Prime Video occurs amid increasing competition in the streaming market. With multiple platforms vying for viewer attention, content libraries have become a key differentiator for services looking to attract and retain subscribers.
Adding recognizable stars like Robert Downey Jr. to the library, even in their earlier works, helps streaming platforms create more discoverable content,” said a media analyst familiar with streaming trends. “These older films often cost less to license than new releases but can drive significant viewer engagement.”
Amazon’s strategy appears to focus on building a diverse library that includes both mainstream hits and cult classics that may have been overlooked during their initial release. This approach allows subscribers to discover films they might have missed while also providing access to familiar favorites.
The complete list of September additions is expected to be announced in the coming days, with the films becoming available for streaming throughout the month. Prime Video subscribers can access these new titles at no additional cost beyond their regular subscription fee.
For fans of Downey Jr., this addition provides an opportunity to see the actor in a role that predates his superhero fame, showcasing the talent that would eventually make him one of Hollywood’s most successful actors.
