Sonakshi shared a throwback photograph of herself, where she is seen with a bruised arm.
"Battlescars are meant to be worn with pride! A memento from when I was shooting an action scene for 'Akira'! (Throwback)," Sonakshi tweeted on Wednesday.
The film is directed by A.R. Murugadoss, who had previously directed Sonakshi in the film "Holiday", which was a success at the box office.
'Akira' sees Sonakshi's character coming to Mumbai from Jodhpur, where she gets into a tiff with the goons of a college, in which she enrolls.
'Akira' releases on September 2.
