'Arrested Development' movie after Season 4 still in the works

Though some cast members have expressed doubt that an "Arrested Development" movie will ever come to fruition -- promising that the upcoming Season 4 on Netflix will come to a satisfactory conclusion for fans in case the film doesn't happen -- show creator Mitch Hurwitz is still confident that it'll happen.

"I'm confident that we will succeed at that," Hurwitz said this weekend at a SXSW appearance with cast members Will Arnett and Jeffrey Tambor. He explained that the 14 new installments, which will debut on Netflix this spring, will leave opportunity for a feature.

"There is a bigger story out there that does exist," he says.
