USA Today has released the first photos from DreamWorks Animation's upcoming sequel Hotel Transylvania 2. They also reveal that comedy legend Mel Brooks has joined the voice cast as Vlad, the father of Adam Sandler's Dracula. His animated alter ego can be seen in the sneak peak images below, alongside other returning characters.

The original Hotel Transylvania, which took in $254 million worldwide in 2012, followed Dracula and the relationship with his daughter Mavis (Selena Gomez), who doesn't like being cooped up in this hotel strictly for monsters. She meets Jonathan (Andy Samberg), the first human ever to set foot inside the hotel, and instantly falls for his less-monsterous ways. The follow-up centers on a family gathering that brings Dracula's father Vlad into town for the first time in several years. His visit creates havoc for Vlad, Mavis, Jonathan and other hotel regulars such as Frank (Kevin James), Wayne Werewolf (Steve Buscemi) and Murray the Mummy (Keegan Michael Key).

Producer Michelle Murdocca reveals that Vlad finds it odd that his son is running a hotel.

"He actually lives in a cave - he is about as old school as it gets. So when he comes and sees that Dracula is running a hotel, he's like, 'What is going on here?'"

Mel Brooks himself had this to say about Vlad's interactions with his son.

"He doesn't treat Dracula with a lot of respect and they're often at odds. It makes for some wonderful comedy."

The actor added that Adam Sandler himself called to offer him the role, and said that he had already worked on perfecting the Dracula accent in 1996's Dracula: Dead And Loving It.

"I had that with me. And I didn't have to make it older because I'm almost 100, so I played it out of my own voice. That Middle-European Transylvanian sound is sweet, it's cute, and if you believe in vampirism, it's correct."

It's also worth noting that Keegan Michael Key is replacing Hotel Transylvania's CeeLo Green as the voice of Murray the Mummy. Take a look at the photos below, featuring Dracula, Vlad, Mavis, Jonathan, Frank, Wayne Werewolf, Murray the Mummy, Griffin the Invisible Man (David Spade) and Eunice (Fran Drescher).
