The Glee actor, who will pen his first book of fairytales entitled The Land of Stories for release next year, confessed that while he loves acting and producing, he most enjoys creating his own original concepts.
"It's tricky because whenever I write or read something I'm incredibly visual. Like when I read the scripts I can practically see shots, the camera angle and all that in my head, but I never really wanted to direct. That's never really my thing," Colfer explained in a new interview with Parade.
"I produce, I love to write. That's really my thing. I think that's my true passion. Writing a character and portraying it. It has to be very, very near and dear to my heart to ever want to direct anything. Like, if I got called to direct a Wicked movie, but other than that, I have no interest."
Colfer went on to say that he occasionally suffers from writer's block, adding: "I don't have writer's block in the sense that I know what the story is, I know who the characters are, I know what they look like, I know what's going to happen. Just putting it into words is a problem that I have.
"Screenwriting and novel writing are so completely different - and I never assumed that they wouldn't be - but I noticed writing a novel, it's like right before you take a trip, and then you get there and it looks completely different than how you imagined and then it's the same. That's how writing is. I've always seen things visually but describing it is the hard part."
Earlier this year, Colfer secured a development deal with the Disney Channel for his series The Little Leftover Witch, based on a children's book by Florence Laughlin.
