A QUICK TRIGGER FINGER: Fox has yanked North Texas-shot Lone Star after just two episodes. The show’s premiere drew a soft 4.1 million viewers. When episode No. 2 dropped by almost a million viewers, Fox pulled the plug. Dallas Film Commissioner Janis Burklund explains to dallasnews.com why the show was on a short leash.

GREEN WITH ENVY: This week, North Texas gets its first look at Shrek the Musical, a Broadway hit that serves as this year’s State Fair musical. But the version we’ll be seeing is a little different from the original. When you tour a show, sometimes elements have to be restructured in the name of portability. Which isn’t to say the experience has necessarily been downgraded. “The Dragon was beautifully constructed, but it was extremely heavy and the creative team knew we couldn’t take that out on the road,” Haven Burton, who stars a Princess Fiona, tells dfw.com. “So they started from scratch and designed this beautiful 32-foot-long dragon that is puppeteered by four ensemble guys.” So we may not be getting the original monster. But we do get a new song for that monster to sing – a solo written just for the touring show called “Forever.”

MORE THAN MEETS THE EYE: How have painters managed to manipulate our brains into thinking that unrealistic images could actually occur naturally? The answer: Science! New Scientist has studied how the brain deconstructs an image to get a better understanding of how artists are able to pull the wool over our eyes. Bottom line: our brains are actually kinda easy to trick.
