Suchitra Pillai did an explicit sex scene with Anoop Soni in the film. The scene was integral to the script and aesthetically handled. Karkash is one of Suchi's best performance till date.
The two-minute long sex scene, along with several other sexual scenes, were omitted from the widely available U/A (PG-13 equivalent) rated version of this film which is available on YouTube with a run-time of 67 minutes. The limited edition DVD version, which is the "A" rated director's cut, runs for over 80 minutes.
