SS Rajamouli, who has adapted several new promotional strategies for "Baahubali", has revealed that he will release the much-awaited audio and trailer of the film on 31 May.

Initially, Rajamouli had planned to make "Baahubali" with a whopping budget of ₹100 crore, but as he went on shooting it, the length and budget of the movie increased considerably. Changing his previous plans, the director has decided to release the film in two parts. The latest reports suggest that the budget of both the parts has reached ₹175 crore.

The makers of "Baahubali" have roped in musician MM Keeravani and lyricist Madhan Karky to create soundtracks for the period drama. Music lovers are eagerly waiting for the launch of its audio, which was earlier slated for release in February 2015, but was postponed due to the delay in composition.

SS Rajamouli, who had kept the looks of all lead characters under wraps, started releasing the posters of the film on 1 May. In the last 16 days, the director has released eight posters, which offers a look at the characters played by Prabhas, Anushka Shetty, Ramya Krishnan, Prabhakaran, Satyaraj, Nassar and Sudeep.

After the eighth poster, Rajamouli revealed that he would release three more posters in the next week and these posters will offer a glimpse of Avantika, Bhallaladeva and Baahubali, played by Tamannaah, Rana Daggubati and Prabhas respectively.

Meanwhile, Rajamouli also announced the date of music and trailer launch of "Baahubali Part 1". On 16 May, the director tweeted, "With that, we come to the final three.. #Avantika on 18th #Bhallaladeva on 20th #Baahubali on 22nd Audio & trailer on may31st #LiveTheEpic."

However, the makers have grand plans for the launch of its audio. The music of both Tamil and Telugu versions of "Baahubali" will reportedly be released at a function to be held in Hyderabad on 31 May.

The makers are going to shell out over ₹1 crore for the arrangements of the event. Many leading stars from Telugu and Tamil film industries are expected to be present on the occasion.
