A Slacker Detective, a Parking Lot and Violence, Violence …

Buzz films pop up all over the weekend

 In the aftermath of South by Southwest’s opening weekend, some buzz films have established themselves — along with the must-see, mind-bender midnight movie of all time.

Choosing the Short Documentary Feature 4 program on Saturday night meant missing the premiere of Aaron Katz’s “Cold Weather,” which became the most talked about film of the weekend. Skipping the world premiere of “Mr. Nice” on Sunday meant attending the world premiere of the fest’s most feel-good film, “The Parking Lot Movie.”

“Weather” (pictured) is about a forensic scientist in Chicago who quits, returns to his hometown in Portland and slips into a deceptively simple routine as he takes a job at an ice factory and re-connects with his old girlfriend. But the tone shifts into a amateur detective story as someone goes missing and he takes it upon himself to solve the mystery.

L.A. Weekly blogger Karina Longworth calls it the first "unqualified hit of SXSW."

Not a narrative doc, per se, “Parking Lot” takes the talking-head approach to give a voice to 21 of the hundreds of lot attendants that approach their job as something akin to a Zen state — when they’re not being screamed out, dealing with drunk University of Virginia frat boys or chasing after people who refuse to pay.

Shot over a three-year period, director Megan Eckman and assistant director Christopher Hlad shift seamlessly from former attendants at a lot in Charlottesville as if it were a group of people all reading from the same script. It doesn’t hurt that a majority of the lot’s employees are collected from UVA’s anthropology, religion and law schools.

Sunday too flight at the Alamo Lamar, with the one-two combo of “Red White & Blue” and “Serbian Film.” The former presents a terse and expertly styled ode to Austin, America and the classic theme of revenge that will make the people who thought “The Killer Inside Me” was brutal drop to the floor in fear.

But it was tame compared to “Serbian.” It’s hard to describe the plot without going into too much detail, but it involves a retired porno actor, his agreement to come out of retirement for one last film and the incredibly gruesome turns taken.

It’s lewd, it’s bloody and it sent more than a few people from the Alamo since they didn’t know what they were in for.

If you’re in Austin on Wednesday, you’ll have one last chance to catch “Serbian Film” before it may disappear forever.
