The adult comedy film "Mastiii 4," starring Riteish Deshmukh, Vivek Oberoi, and Aftab Shivdasani, is set for its OTT release on Zee5 on January 16, 2026. Directed by Milap Milan Zaveri, the movie revisits the franchise's signature humor but received a lukewarm response and underperformed at the box office, earning approximately ₹15-19 crore against a ₹40 crore budget. The film, which explores themes of marriage monotony and relationships, also features a large ensemble cast. It previously had a theatrical release on November 21, 2025, with an 'A' certificate.
