Sonakshi Sinha will adapt the 1980s' disco style of dance for "Thank god it's Friday", a special song in "Himmatwala" remake.
The song, to be choreographed by Chinni Prakash, will have almost 100 dancers and 400 extras, said a source.
"It is a retro disco number which will have reflective dance floors, mirrors and everything shiny and glamorous," the source added.
And Manish Malhotra has designed Sonakshi's dress for the song.
The actress had earlier grooved with Prabhudheva in the song "Go go Govinda" for the film "OMG: Oh My God!".
"Himmatwala", a remake of 1983 hit movie of the same name, is being directed by Sajid Khan. It features actors Ajay Devgn and Tammanah.
Co-produced by Vashu Bhagnani and UTV, the movie will hit theatres March 29.
