Hulu Original mystery-comedy “Only Murders in the Building” follows three strangers (Steve Martin, Martin Short, and Selena Gomez) who launch an investigation and podcast when a murder happens in their apartment building. In season 4, a movie adaptation of the podcast is central to the mystery storyline. Ahead of the launch of season 4, Hulu released a digital campaign of promos that heavily feature behind-the-scenes interview footage to entice viewers based on the charm of the cast and breadcrumbs of mystery clues peppered throughout. Interviews with cast and crew talk about the filming fun, the challenges, and the unique experiences regarding filming part of the series in Los Angeles, a far cry from the New York City-based series. The basic plot elements for Season 4 are lined up, priming audiences for the opening moments of the season, without revealing too much about the twists and turns the plot will take further down the line. The campaign's videos each focus on different parts of the season, such as being in the Los Angeles filming experience, the actors set to play the main trio in the film adaptation, or the brand new characters in the West Tower of the Arconia (the NYC apartment home of the main trio). The campaign utilizes the same high-energy, fun-but-tense air of mystery across all elements, ensuring that the same aesthetics, tone, and appeal for the series proper are maintained. Similar audio cues, editing style, and comedic timing are utilized, ensuring that even the behind-the-scenes videos feel like they are part of the same world as The Arconia. The campaign aims to draw in audiences that are fans of the series with a focus on a bigger whodunnit than previous seasons, mystery-lovers with the unique setting, and comedy aficionados with its bevy of high-profile cast members.
