AceShowbiz - Plans to reboot 1970s TV drama "The Rockford Files" have been shelved for a second time after producer David Shore was forced to return to writing duties on his hit medical drama "House M.D.".

Shore had planned to script and produce a rejuvenated "Rockford Files", which originally starred James Garner as private investigator Jim Rockford, and was rumored to be in talks to sign up "Lost" hunk Josh Holloway for the lead role.

However, after a huge section of the new House series was scrapped at the last minute, creator Shore had to return to help re-structure the season, leaving his new project on hold, according to Deadline.com.

It is Shore's second attempt to revive "The Rockford Files" - a previous reboot, starring Dermot Mulroney as Rockford, failed to get past the pilot stage after NBC bosses gave the episode lacklustre reviews in 2010.
