Abhijit Panse's Thackeray, which stars Nawazuddin Siddqui in the lead role, has managed to collect Rs.31.60 crore within a week's of it release, reports Bollywood trade analyst Taran Adarsh.

The biopic opened in theaters last week and it clashed with Kangana Ranaut's Manikarnika: The Queen Of Jhansi.
