Reentry into cinema (2013–2015) Vanitha made a brief comeback to acting in the mid-2010s, and first appeared in a small role in
Naan Rajavaga Pogiren (2013). She followed this up with a longer role in the comedy drama,

MGR Sivaji Rajini Kamal (2015), to be directed by her then-boyfriend
Robert. She produced the film under the Vanitha Film Production banner, suggesting that the script of the film originated from a joke they discussed at a social gathering.

She was also rejected by most directors and didn't receive any film offers from directors, and she decided to quit acting for some time due to criticisms.
