The Godzilla star spent the first two hours of his day in the make-up chair while shooting the family comedy to transform himself into the evil character Gargamel.
But he reveals his toothy grin caused a series of delays during production because the fake dentures wouldn't stay put.
He tells WENN, ""They gave me a set of teeth right in the special effects shop. Those teeth would fly out of my mouth a lot every time I yelled or any vibration would make them dislodge. Many a take was ruined because the teeth would come flying out, which was not a great moment.""
However, there was one part of his character's behaviour that Azaria had fun with: playing around with his feline co-stars - although he assures animal lovers the pets were well looked after on set.
He says, ""I find them amusing and I enjoyed throwing cats in the movie. No cats were harmed I must say but I did get to toss the cat quite a lot. The good thing is cats don't care because they just land on their feet and move on as if they meant it to happen.""
