It’s been a while, but Joss Whedon promises to add a dash of  harmonious horror to the summer by finally beginning filming  on the long-awaited Dr. Horrible’s Sing-Along Blog 2.

The Whedon clan have been relatively tight lipped about what we can expect from the upcoming season, but Joss has promised that soon enough patient fans will have answers.

In a recent interview Joss Whedon had this to say; "We’re stuck, basically, at this one part in the process. All of us are looking at this summer as the time when we can go, ‘Hey, you know what? We’ve got a little free time, let’s get unstuck.’ Neil has been like, ‘How long?’ We’re all sort of just waiting, but the waiting will stop."

Whedon goes on to add that he’s got a “number of songs” written, and “a whole outline.” What exactly that outline consist of is currently a secret, but with Dr. Horrible becoming a proper super villain and with no official word if Felicia Day will reprise her role as Penny, fans of the award winning musical web series can rest assured that even after nearly four years the Whedons have more toe-tapping evil hilarity coming for series two.

Joss Whedon has always been the king of multitasking, but lately he’s been putting that skill to the test. Between directing a little project known as The Avengers, filming an adaptation of Much Ado About Nothing, writing the screenplay for the upcoming Chris Hemsworth flick Cabin in the Woods as well as finally completing the post-apocalyptic series Wastelanders with writer Warren Ellis -- Whedon has a lot on his plate since the 2007-2008 writer’s strike which gave birth to Dr. Horrible.

The brainchild of writer and director Joss Whedon, along with writer brother Zack Whedon and composer brother Jed Whedon, Dr. Horrible’s Sing-Along Blog was designed as something inexpensive and quick to shoot—Shortly after its 2008 debut, the musical tragicomedy became a breakout hit internet sensation.

Released online in three acts, the first installment of Dr. Horrible’s Sing-Along Blog revolved around the titular character Dr. Horrible (Neil Patrick Harris) as an aspiring supervillian who melodiously stalks young Penny (Felicia Day), a girl from the laundromat. Foiling Dr. Horrible’s villainous and romantic plans is the dimple-chinned Captain Hammer (Nathan Fillion) who is more of self-centered super bully than super hero. The final act of series one found Dr. Horrible achieving his evil goal – So what does that mean for series two?
