Waah! Tera Kya Kehna

'Waah! Tera Kya Kehna' (English: Wow! You're Amazing) is a 2002 Indian Hindi-language comedy film directed by Manoj Agrawal starring Govinda and Raveena Tandon.

Plot
Krishna Oberoi, a distinguished businessman, has two sons, Dilip and Ashish, who he suspects are primarily interested in his wealth. He prefers his devoted grandson, Raj, whom he plans to entrust with his estate. Raj, deeply loved by Krishna, is also enamored with Meena. Their relationship culminates in an engagement, but a tragic accident leaves Raj with brain damage, exhibiting childlike behavior, and ultimately leading to the engagement being called off.

Amidst these troubles, a conspiracy by Dilip's son Vikram forces Raj to separate from his grandfather, taking refuge with Murari. Heartbroken by Meena’s decision not to visit him, Raj disappears into a sandstorm. During this chaos, Dilip, Ashish, Vikram, and their accomplice Charles orchestrate Krishna’s murder, drugging him and then throwing him from a building.

In a twist of fate, Murari encounters Banne Khan, a striking doppelganger of Raj, along with his wife, Salma Khan, and their assistant. Murari convinces Banne to impersonate Raj to claim his inheritance and exact revenge. As Banne steps into his role, the real Raj unexpectedly returns; the two lookalikes confront and defeat Raj's uncles and Charles, restoring justice and order to their lives.
