One scene, filmed Wednesday at Madison Square Garden, had Will Arnett's character, Vern Fenwick, at a basketball game with his apparent girlfriend, played by Victoria's Secret lingerie model Alessandra Ambrosio. (Convenient, considering the last shot of the first movie.) During filming, the two shared a bag of popcorn and, apparently, at least one kiss.
During a podcast interview with The Lowe Post, LA Clippers star J.J. Redick detailed, that he, along with fellow Clippers Austin Rivers, Matt Barnes, Spencer Hawes, and DeAndre Jordan were featured in the filming along with five Knicks players. He also let slip that the title might be "Teenage Mutant Ninja Turtles: Half Shell."
Of course, shooting titles are subject to change, so it's hard to take any meaning from this.
