It's strange that you should ask, because though there are no current plans to remake the influential '70s crime show, there were once.

Around the same time CBS was looking at the "Hawaii Five-0" remake, it was also talking about a remake of "The Streets of San Francisco," the now-classic cop show that starred big-screen legend Karl Malden and then-young upstart Michael Douglas as partners patrolling the streets of the city on the bay. When Douglas's big-screen career started to take off by the late '70s he left the series, to be replaced in the final season by Richard Hatch.

Had things worked out differently the upcoming fall TV season could have ended up awash with muted Earth tones, with not two but three '70s cop shows getting the revival treatment. While the "Hawaii Five-0" and "Rockford Files" remakes made the cut for this fall, a once-discussed "Streets of San Francisco" redo didn't make it further than the CBS recycling bin.

In fact, CBS had its eyes on San Francisco weeks before it looked across to Hawaii. Or at least the news broke that way.

Word came out that "Numb3rs" producer Robert Port was working with big-screen scribe Sheldon Turner (who most recently wrote the script of the 2009 George Clooney hit "Up in the Air") on a "Streets of San Francisco" remake in July 2008. It wasn't until mid-August that talk started coming out about the "Hawaii Five-0" remake.

But while work progressed on the "Five-0" project (albeit after a one-year delay), the "Streets of San Francisco" series was never heard from again.

As mentioned, NBC has its own entry into the cop-show revival competition this fall. The network is launching a new "Rockford Files," starring big-screen romantic-comedy leading man Dermot Mulroney in the title role.
