Chennai, Mar 16 (IANS): Actor Nandamuri Balakrishna, who is busy finalising the script for his highly anticipated 100th project, is toying with the idea of working with directors Krish Jagarlamudi or Krishna Vamsi.

"Although a few days back, director Krishna Vamsi declared that Balakrishna had chosen him to direct his 100th film, it looks like director Krish is still in the race as Balakrishna, who is impressed by both their scripts, is yet to lock one," a source close to the actor told IANS.

By March-end, Balakrishna is expected to officially announce details about his 100th film, the source added.

"Since it is his 100th project, he is being extra careful. He wants to choose to right script and doesn't mind waiting a few more months in the process," he said.

Director Krish, meanwhile, is getting ready to begin work on his next Hindi directorial.

Krishna Vamsi, on the other hand, has postponed the shoot of his Telugu horror fantasy "Rudraksha" to begin work on his project with Balakrishna.
