The film
578: Magnum is a 2022 Vietnamese action film: a truck driver hunts down the people who harmed his daughter, across a road movie's worth of fights, chases and a boxing ring. Vietnam released it as 578: Phát Đạn Của Kẻ Điên, and it travelled abroad under the Magnum title. It is on this site under its own page, with the cast, the runtime and a Watch now button that lists the services carrying it in your country, and it is what most people typing "578 movie" into a search engine are after.
The site
578Movie is a movie and TV site that shares the number. It lists titles with their seasons, their dated episodes and a Watch now button for your country, Hollywood first, with a Vietnamese shelf that begins with the film. It has no connection to the film's producers and makes no claim on the earlier sites that carried the name. The number is a name, the way a street number is; the site is what is behind the door.
Finding the film and the ones like it
Search 578, Magnum or the Vietnamese title; all three open the page. The Vietnamese shelf holds the rest of the industry's films and series in the catalogue: Furie and Furies for the action, Mai and Sister Sister 2 for the box-office dramas, Inside the Yellow Cocoon Shell and The Third Wife for the festival films, Devil's Diner and Hellbound Village for the series. The action shelf holds the Hollywood films most often watched alongside them.
Where the film streams
Set your viewing country and press Watch now. Vietnamese films travel unevenly: a title on a global subscription in the United States may be on a local service in Vietnam and on a rental store alone in the United Kingdom, and the free ad-supported tiers carry a surprising number of them. The Watch now list changes with the country menu, which is why the menu sits above the button.
