Indian biopics are often not true biopics; they are fictional dramas. Why is that? It's difficult to answer. Maybe drama is inherent to Indian culture, which is why ancient Indian literature is rich in poetry (which is always more dramatic than prose). Prose came much later.
Tumko Meri Kasam is a biopic on IVF specialist Dr Ajay Murdia, the founder of the nationwide chain of fertility clinics Indira IVF. In fact, the doctor himself has produced the movie, with Vikram Bhatt as the director. Sadly, this film has also slipped into the drama category, straying far from reality.
