Flight of the Conchords by Nicole Rivelli/HBO
Flight of the Conchords ' next season take-off may be its last.

According to The New Zealand Herald, famous sons Jemaine Clement and Bret McKenzie shared with British magazine Q that they were seriously mulling ending the series after the second season due to the creative struggles they've encountered in making it.

"The second series seems to me like it would be a good end to the show," McKenzie said. "I feel like another 10 [episodes]... that will be enough."

The duo, which used already written tunes in the show's first season, is still in the process of writing the new music narratives, which they've found "difficult."

"We've got a lot of half-songs," Clement said. "We've got an album's worth of beginnings of songs."

Season 2 of the HBO cult hit was scheduled for a 2008 bow, but has since been postponed until next year. The comedy is up for four Emmys this month, including two in the Original Music and Lyrics category. - Joyce Eng
