Because of it being the first major science-fiction miniseries since ‘Steven Spielberg’'s "Taken" (2002), and because of its nearly opposite premise, it is jokingly renamed by sci-fans as "Put Back".
The opening scene played at the beginning of each episode, which explains the premise of the series, is 44 seconds long.
When the producers were conceiving of the series, the secret of who had abducted the 4400 was supposed to be revealed in the fifth season. USA had picked the show up as a miniseries and wanted it to have some resolution, so the secret was revealed in the fifth episode.
The address of The 4400 Center, 6265 Crescent Road, is the same as The Chan Centre for the Performing Arts, University of British Columbia, Vancouver.
For advertising the show, stock images were purchased from various stock image agencies to create a variety of people to show as part of the 4400 missing people. This was most likely to avoid paying various actors to use their image for the advertisement purpose.
