Ravi Teja is known for energetic special songs. SS Thaman, who is always in his elements in dishing out peppy songs, has often whipped up cackling numbers with Mass Maharaja. 'Krack' brings them together and it's only fitting that director Gopichand Malineni has infused a special song in the movie.

Apsara Rani, the heroine of RGV's 'Thriller', has been roped in to shake the leg with the 'Disco Raja' actor. The song was shot earlier this week at Annapurna Studios on the Ravi Teja-Apsara duo and a group of dancers. A few Behind-The-Scenes stills are out.

The shoot of the action entertainer, which stars Shruti Haasan as the heroine, is in its final leg. Produced by Tagore Madhu, the film also features Varalaxmi Sarathkumar and Samuthirakani. Dialogues are by Sai Madhav Burra.

The film's release date is yet to be announced.
