saiyaara movie remake of which movie

The movie "Saiyaara" is based on the 2004 Korean film "A Moment to Remember." Although there has been no official statement from the makers of "Saiyaara" declaring it an official remake or adaptation, many fans and critics have pointed out striking similarities in the plot, especially the theme of early- onset Alzheimer's affecting the love story. Despite the resemblance, "Saiyaara" is credited with an original story by Sankalp Sadanah and Mohit Suri, framed for Indian sensibilities, and regarded as a contemporary Indian love story. The Korean film itself is based on a 2001 Japanese television series titled "Pure Soul." Thus, while "Saiyaara" may participate in a larger lineage of storytelling involving similar themes, it is widely recognized as inspired by or based on "A Moment to Remember".
