The actor can currently be seen opposite Mallika Sherawat in Kismet Love Paisa Dilli.
He told Bollywood Hungama: "Rakhta Charitra was a very intense film and I still feel that it was one of my most difficult roles. Just getting into the skin of the character was such a difficult thing and moreover it was made in different languages and two parts.
"It was a very intense exercise for me and I wanted to take a break after that. I just wanted to disappear for six months. In any case I had just got married and a holiday was due."
Oberoi took on the role of political leader Paritala Ravindra in the biopic Rakhta Charitra.
In January, it was revealed that Oberoi was dropped from the action sequel Shootout at Wadala.
However, he will be reprising his super-villain role in the Krrish action franchise next year.
