Gautham Vasudev Menon, even as busy filming his first trilingual venture 'Neethane En Ponvasantham', seems to have zeroed in on the heroine for 'Yohan Adhyayam Ondru', his maiden film with Vijay.

If sources are to be believed, Gautham's 'favourite actress' Sameera Reddy would share the screen space with the Ilayathalapathy in this big-budget venture, which is set to hit the floors by early 2012.

"But an announcement is kept under wraps since Gautham wants to complete Neethane En Ponvasantham, before shifting focus to Yohan Adhyayam Ondru. Vijay too is happy to have Sameera on board," sources say.

Sameera was the leading lady of two of Gautham's earlier movies- 'Varanam Aayiram' and 'Nadunisi Naaygal'. In an interview earlier, the actress mentioned that she would act in a film without even listening to the script, if it is directed by Gautham.
