Malayalam superhit movie Manjummel Boys is a production venture of film's star Soubhin Shahir, his father Babu Shahir and Shawn Antony of Parava Films. These makers found themselves in hot water after an investor named Siraj alleged of "cheating" and "financial fraud", claiming that he invested Rs. 7 Cr. on the movie but did not receive a penny as a return on his investment.

Manjummel Boys which is estimated to have grossed Rs. 242 Cr+ in box-office collections, was made on a measly budget of Rs. 20 Cr+. Siraj, a resident of Aroor, had alleged this was an inflated number. He stated in his petition that producers made Siraj believe that there was a 40% share of profits on an investment of Rs 22 Cr, whereas Manjummel Boys was made only with a budget of Rs. 10 Cr, of which he invested Rs. 7 Cr. 

Another misrepresentation that Siraj had alleged of was that the the Manjummel Boys producers misled Siraj into believing that the first shooting schedule had been completed, when in reality, it had not even commenced. Manjummel Boys released in theaters on February 22, 2024 and within 2 weeks of the film's release, Siraj had taken the makers to Ernakulam First Class Magistrate Court. 

On April 13, 2024 the subordinate Ernakulam court directed a bank to freeze the accounts of the Manjummel Boys producers, based on Siraj's petition, and on April 24, 2024 it directed the Maradu Police to book a case against the producers on charges of cheating and conspiracy. The Kerala High Court on May 4, 2024 intervened in this filed case of 'criminal conspiracy, breach of trust, and forgery', and stayed the arrest of Soubhin Shahir, Babu Shahir and Shawn Antony till May 22, 2024. 

Latest update on this controversy is that the Kerala High Court has been presented with a police investigation report, which implicates the producers of Manjummel Boys. However the discrepancy found by the Kerala police is unlike what Siraj had alleged in his petition (Rs. 10 Cr. spent, Rs. 22 Cr. shown), and is submitted to be Rs. 18.65 Cr. spent, as opposed to the assumed Rs. 20 Cr+ spent in production costs.
