The 24-year-old Sara said she "can't believe it's been a year" and mentioned that the film "has been and will always remain an integral part" of her life.
The actress, who made her Bollywood debut with the Abhishek Kapoor directorial on December 7 last year, also thanked the entire team of the film including her co-star Sushant Singh Rajput.
Sharing a few stills from the sets of "Kedarnath" on Instagram, the actress wrote: "I can't believe it's been a year since everyone met Mukku for the first time. Kedarnath has been and will always remain an integral part of me. Thank you @gattukapoor and @kanika.d for making me meet, imbibe and portray Mukku."
"@sushantsinghrajput I truly appreciate all that you did to support me and help me consistently throughout this journey, I couldn't have asked for a better Pithoo to carry me through all of this! Thank you Tushar Sir for shooting this film with so much love."
"@jehanhanda thank you for constantly having your eyes on me and always having my back. And thank you to all the people that have accepted me, given me so much love and allowed me to be a humble part of the Indian film industry for a year now! #jaibholenath".
Sara, whose second release "Simmba" opposite Ranveer Singh, happened a few weeks later on December 28 2018, will next be seen alongside Varun Dhawan in "Coolie No.1". The film is a remake of director David Dhawan's 1995 superhit comedy of the same name, starring Govinda and Karisma Kapoor.
The actress will also be seen in Imtiaz Ali's untitled film opposite Kartik Aaryan which is scheduled to release on Valentine's Day next year.
