Here's why:
* Varying definitions of "opening logos": Does it include the entire opening sequence (like the Universal logo followed by the Amblin logo)? Or just the logo itself?
* Different film formats: Some films have extended opening sequences that are only shown in certain formats (like theatrical releases).
* Limited data: It's hard to find a comprehensive list of every film's opening logos and their durations.
However, here are a few films known for having particularly long opening sequences:
* The Lord of the Rings: The Fellowship of the Ring (2001): The opening sequence, featuring the iconic "One Ring" logo, lasts about 1 minute and 40 seconds.
* The Lord of the Rings: The Two Towers (2002) and The Return of the King (2003): These films also feature the extended opening sequence, similar to the first movie.
* 2001: A Space Odyssey (1968): The opening sequence, featuring the famous "Dawn of Man" montage, lasts about 9 minutes. However, it's not strictly a logo sequence.
* Interstellar (2014): The opening sequence features a unique, abstract logo and lasts for about 2 minutes.
* Gladiator (2000): The opening sequence, showcasing the iconic "DreamWorks" logo, lasts for about 1 minute and 30 seconds.
To find the absolute longest opening logos, you'd need to research specific film databases or watch a large sample of films.
