"I wanted Rekha madam to play Vishal's mother. We wanted her to shoot with us for a few days but since she was extremely busy with prior commitments, we couldn't sign her on," Hari told IANS.
Instead of Rekha, Hari has roped in Tamil actress Radhika for the same role.
Rekha, who is a south Indian by birth, is the daughter of late legendary Tamil actor Gemini Ganeshan. She made her cinematic debut with Telugu film "Rangula Ratnam".
"Poojai", which is currently on floors in Coimbatore, features Shruti Haasan as a female lead.
