I'm looking it in different angle. An actor will Voluntarily come, raise his/her voice and support for issues which are not going to affect his/her business instead it will boost his/her image.
Just an example, hogenakkal protest time'la Mr.Sathyaraj ennanamo pEsunaaru. Ippo, Next month Nanban movie release vechikittu antha maathiri malayaleesa paathu pEsuvaara. Production house'la irunthu dicky laye adipaanga.
Ungalukku image boost aaganumna neengala vanthu oora kaapaathuveenga, business adivaangumna irukura edame theriyaathu.
Poovaraagan,"Unakku vEnumna thottukuva, vEnaamna thodamaata".
