The Lord of the Rings TV series has finished filming its first season. The season is expected to premiere on September 2, 2022, with new episodes available weekly, but a series like this is likely to involve complicated visual effects, meaning a lengthy post- airing period. When it does debut, the series will only be available on Amazon's Prime Video streaming service.
The Second Age is a time period that is mentioned in The Lord of the Rings but that has not been depicted in the new series. The opening battle scene of Peter Jackson's The Fellowship of the Ring is included in those flashbacks. That sequence caps the centuries-long Second Age and marks the beginning of the Third Age, which is when The Lord of the Rings books and movies take place.
It's worth noting that the movies had several unknowns who went on to fame after they debuted, like Viggo Mortensen. J.D. Payne and Patrick McKay are likely to be unknown to audiences."
