Trailers? Check.

Street closed? Check.

Bright lights? Check.

Spike TV's "The Kill Point" has brought all the tell-tale signs of Hollywood to Downtown Pittsburgh this week as the eight-hour summer series enters its second week of production.

Star Donnie Wahlberg was glimpsed taking a break outside his trailer on Third Avenue Tuesday around 1 p.m.

Wednesday morning, Fourth Avenue was closed as cameras were trained on the driver of a blue Jeep Grand Cherokee parked in front of the Investment Building.

Extras wandered back and forth on the sidewalk across the street from the Jeep, offering background motion. Director Steve Shill watched the action on a monitor under a nearby tent. Faux cops meandered in a nearby parking lot, waiting for their turn in the bright lights.

When I checked back at 1:15 p.m., a cadre of black-clad SWAT team members were being filmed running down the sidewalk for a scene from episode four. ("The Kill Point" is using a collapsed, complicated shooting schedule, filming the first four episodes simultaneously rather than one episode at a time.)

This week's production is just the start of outdoor, on location shooting. Pittsburghers are likely to see evidence of Hollywood around town in the coming weeks not just from this TV show but also from a Blair Underwood-directed film that's in production.

"The Kill Point" will make its biggest public splash in mid-May when production takes over Market Square for eight weekdays. Transit riders can expect plenty of Forbes Avenue bus re-routing when that happens.

Today "The Kill Point" will continue shooting around the edges of Market Square, but the scenes will be with snipers, so look to the rooftops if you hope to see them.

I have to credit the TV folks with being super easy-going about their public disruptions. After seeing the evidence of filming (including a fake TV news truck for a station that doesn't exist, WWEJ, "News Watch" Channel 14), I sniffed out the production crew yesterday morning while en route to the office.

A production assistant asked me to wait on the sidewalk while a scene was filmed -- so as not to mix in with the background extras in sight of the camera -- but then I was allowed to pass and scope out the doings.

If you see the crew out and about, be respectful, but don't be afraid to do a little bit of gawking. It's fun to watch for a couple of minutes and then quickly grows boring.

I'll continue to monitor "Kill Point" production and mention it here occasionally. Feel free to e-mail me (rowen@post-gazette.com) if you have your own noteworthy encounter with the "Kill Point" crew.
