Colin Farrell, who starred as Holt in Dumbo, has said that he was astonished by the set design of the film even though most of it was green and blue screens. The circus seen in the film was built inside a sound stage and had about 300 LED lights to create various effects such as sunset, sunrise, and several other weather conditions.

"This is like nothing I have ever seen before! I mean, from the ground up, even the corner parts of the set that'll never be seen on camera and the attention to detail, you know. It's just - you go in one door and it's one world, you go in another and it's an another world. It's pretty astonishing really! And it's great as an actor because it just allows you to inhabit the world," said Colin.

"It's just as you have heard before I'm sure. It does so much of work for you. So there's blue screen everywhere because skies will be filled in after a certain height, buildings will be created and stuff but anything that I see or interact with, anything I touch or feel or refer to, has been there," he added.

The film will be available for streaming on Star Movies from May 3 in India.
