Keerthy Suresh won appreciation for breathing life into the reel character of legendary actress Savitri in the biopic Mahanati. She also won National Award for her outstanding performance. But, Keerthy was initially hesitant to sign the project. She felt that she might not do justice to the role and hence decided to turn down the offer. However, Keerthy is also glad that Nag Ashwin was determined to cast her in the biopic despite her refusal in the first attempt. Now, Keerthy will appear playing a mother role in the upcoming crime drama titled Penguin that is set for a digital premiere on 19th June on Amazon Prime.
