The last time they shared screen space was in the 2005 movie Waqt - The Race Against Time.
"The shoot of Bhootnath Returns with the wonderful and most affable Boman Irani. Always a joy. Working with him after Waqt," Amitabh Bachchan tweeted on Wednesday.
Boman thanked him for his kind words.
"Thanks Mr. B for your warm words. Always a pleasure to meet you," said Boman.
