Wittrock, who played psychopath Dandy on the fourth season, feels that 29-year-old Gaga is the perfect choice of the show, reported Variety.
"I was like, 'Perfect!' Ryan (Murphy) always has a way of outdoing himself. It's hard to keep surprising people when each season is so surprising.
"He very wisely makes a big awesome casting choice to get people intrigued. This was the epitome of that." he said
The 30-year-old "Freak Show" actor thinks that the theatricality Gaga has is what is needed in the show.
"The show is heightened and gothic and that's sort of what she is. It's a good omen for the way the season will turnout," he added.
