There is one superpower the actor Tom Welling, who plays a young Clark Kent in “Smallville,” would love to have in real life. “I wish I could split into two people,” he said on the phone recently, running late after wrapping a scene. “I desperately want to be in two places at once.”

Welling, 33, was referring to two specific places, both of them in Vancouver, British Columbia: the set of the show he stars in, “Smallville,” now entering its 10th and final season, and the set of “Hellcats,” a new CW drama beginning tonight on which he is an executive producer.

“Smallville” — and Welling — started on WB, a now-defunct network that became a teen-programming destination with shows like “Gilmore Girls” and “Buffy the Vampire Slayer.” When CW absorbed WB, “Smallville” stayed on the air, its wholesome earnestness somewhat out of place among the network’s stable of scandalous, hormonal dramas. So network executives didn’t expect a pitch for “Hellcats,” a cheerleading story with the tag line “Hell hath no fury like a cheerleader scorned,” to come from Welling.

“I was surprised that this was something he was interested in,” said Dawn Ostroff, the president of CW. “But whether or not it’s his personal taste or instinct, he knew it would fill a niche.” “Hellcats” joins a CW lineup that includes “Gossip Girl” and “90210” — and like those shows, it features a gorgeous ensemble cast, sharp-tongued writing and a carefully tailored cool-kids soundtrack.

It has something those shows lacked when they made their debuts: stars. Whereas CW dramas tend to make celebrities out of their casts, “Hellcats” has two leads who are already well known to the young audience the network covets: Aly Michalka (“Disney 365,” “Bandslam”), who is best known as half of the pop sister act Aly and AJ, and Ashley Tisdale of “High School Musical” fame.

And it has Welling.

Many actors on long-running series garner producing credits, some more or less symbolic. “There’s a huge difference between being the lead of a show and being its leadership,” said Kelly Souders, an executive producer on “Smallville.” “But Tom’s an extremely hard worker, and as he took on more responsibility and grew this understanding of what it is to get a show off the ground, he still wanted to be more and more involved.”

Souders, who works from Los Angeles, said she knew Welling was serious about directing and producing when she began to notice him in the background of her video-conferencing screen. “I’d be in a production meeting with people in Vancouver, talking about an episode he wasn’t directing, and I’d look up and he’d be sitting on the end, just listening in.”

Crammed as his agenda already was, Welling could not resist a book that landed on his desk several months back from his agent. It was “Cheer!,” an exploration of college cheerleading by the journalist Kate Torgovnick. Welling found himself captivated by the athleticism and competitive subculture. “There are people who stay in school just to cheer,” he said, “and I didn’t know that existed.”

With Warner Brothers on board, Welling and his production company assembled a team: Kevin Murphy (“Caprica,” “Desperate Housewives”) would write and produce the pilot; a crew stocked with “Smallville” veterans would help shoot it; and Allan Arkush (“Heroes,” “Crossing Jordan”) would direct. Arkush said that since Welling himself is the lead in a series, his input in casting Marti, the reluctant cheerleader at the center of the series, was invaluable. “It’s not just about the right actor,” Arkush said. “The lead has to be the type of person you’d want in your home.”

The role ultimately went to Michalka — after she completed a second, more physical round of auditions. “Every time you watch ‘Hellcats,’ you’re going to see a performance,” Welling said.

If her audition was grueling, it was nothing compared with her workload for the pilot, which called for running, biking, jumping and flipping more typical of an action movie than a teenage drama. “We just put her through hell,” said Murphy, also an executive producer. “She had bruises head to toe. Having Tom there to say to her and to all of the cast, ‘I’ve been there, it’s going to get better,’ was of incredible value. As far as reassuring presences on your set go, you can’t do much better than Superman.”
