And now Im back in the graveyard again.

We have a lot of great guest stars on the show this season, Clement says.

Fans will see Haley Joel Osment in the premiere.

WHAT WE DO IN THE SHADOWS

Russ Martin/FX

Everyone fell in love with him!

Hes a really talented actor, obviously.

And we had no idea how funny he is.

He only appears in one episode but its a huge character change.

He gets to play on the other more scarier side.

He adds, He came in for an audition and we were surprised to see him.

He did a great audition.

Topher is instantly a hit with everyone, except Guillermo [Harvey Guillen], Osment explains.

Hes a threat to his position in the house.

The vampires dont treat Guillermo well, and here comes Topher with so many qualities they admire.

This creates a lot of tension.

He adds, The house is a dangerous place and some things happen to him.

Luckily, the vampires dont care and they still keep him around, even if hes a limb short.

Guillen says Guillermo fans neednt worry too much about him this season.

A thankless job, obviously, Guillen shares.

I dare anyone to underestimate Guillermo because hes ready!

Nadja and Laszlo havent had much luck with picking familiars.

So when they finally find this young guy Topher, theyre so excited.

Hes the new guy, and to them, seems so much cooler and hipper than Guillermo.

A fun bit of behind-the-scenes trivia for you, Osment says cheekily.

I had an arm mutilated onThe Boysin Toronto last year and it was still hanging around in a warehouse.

Some of the effects people fromThe Boyswere working onWhat We Do In The Shadows, funny enough.

Osment is hoping that technicality will allow him to play in this world as Topher again one day.

I definitely dont think its the last time weve seen Topher.

Fans will see a lot more of the creatures and things that live in the underworld of Staten Island.
