Keanu Reeves in a hidden role

Keanu Reeves appears briefly in Joker as part of an old Kellogg's Corn Flakes commercial that plays on a television screen during a chaotic scene. His appearance is nearly imperceptible and requires precise timing to spot.

The timeline inconsistency

The Kellogg's commercial featuring Keanu Reeves was broadcast in 1987, but Joker is set in 1981, creating a six-year discrepancy. This anachronism is one of several in the film that suggest the fictional Gotham City is not strictly bound to its intended time period.

Other modern elements in the film

The film includes other elements that are out of place for its 1981 setting, such as the Energizer Bunny, which first appeared in 1988, and a storefront offering mobile phone repairs, which would not exist until years later.

Modern vehicles and technology in 1981 Gotham

Joker also includes modern vehicles and technology that were not available in the 1980s, such as a Citi Bike station and a fourth-generation Ford Econoline ambulance, both of which were introduced well after the film's setting.

The film's success despite inconsistencies

Despite these anachronisms, Joker was a massive success, winning two Oscars in 2020 and earning critical acclaim for Joaquin Phoenix's performance. The film's unique atmosphere and storytelling overshadowed these minor details.

Where to watch Joker and its sequel

Joker is available for streaming on Netflix and HBO Max, while its sequel, Joker: Folie à Deux, is available on VOD platforms. Fans can revisit the film to discover hidden details like Keanu Reeves' cameo.
