One thing you learn fast about those Wisconsin Film Festival fans — do not dilly-dally around them.

Tickets went on sale at noon Saturday at the 15th annual festival’s box office in Union South (and online at wifilmfest.org), and in less than an hour folks were already reporting the first sellout.

Ahem. Called it!

While I was correct in prognosticating that the much talked-about “Much Ado About Nothing” was the first film to sell out (prompting one follower on Twitter to accuse me of witchcraft), take heart. The film opens in its regular theatrical run on June 21, making a return to Sundance Cinemas this summer a certainty.

Here’s the other films that, based on a Monday morning perusal of the online schedule at wifilmfest.org, sold out over the weekend. Where possible I’ve tried to denote which films have alternate screenings for which tickets are still available. In addition, the festival has left some programming wiggle room in the back half of the festival so it can book additional showings of hot films. I’ll update this list periodically, so keep an eye here and, of course, at wifilmfest.org.

“56 Up” — all three screenings are sold out. One of the subjects of the doc, Nick Hitchon, will be speaking at the Saturday screening only.

“7 Boxes” — The 5:15 p.m. Friday show is sold out, but tickets remain for the 9 p.m. Tuesday.

“Breakfast with Curtis” — 11:30 a.m. Saturday is sold out, but tickets remain the 12:15 p.m. Friday show.

“The End of Time” — 11:15 a.m. Saturday is sold out, but tickets remain for 12:30 p.m. Friday.

“Flicker” — 7:45 p.m. Saturday is sold out, but tickets for 12:15 p.m. Friday and 4 p.m. Monday remain.

“Key of Life” —  7 p.m. Wednesday is sold out, but tickets for 1:30 p.m. Thursday remain.

“Kon-Tiki” — 6:30 p.m. Sunday sold out

“Lore” — both screenings sold out

“M” — 7:30 p.m. Saturday sold out

“Much Ado About Nothing” — 9 p.m. Thursday sold out

“Pretty Funny Stories” — 5 p.m. Saturday sold out

“Short Films From Wisconsin’s Own” — 2 p.m. Sunday sold out

“Stories We Tell” — 6:45 p.m. Thursday sold out

“The World Before Her” — 7:30 p.m. Friday sold out

By my count, that leaves tickets available for 12 of the 15 movies on my can’t-wait-to-see list still available.
