Bollywood actor Kartik Aryan says playing two distinct characters from different eras in Imtiaz Ali's upcoming film Love Aaj Kal was a challenge he enjoyed.

The film shows love stories of two different eras, the first is set in the late 1980s–early nineties, and unfolds between Raghu and Leena. The other love story, set in the present time, happens between Veer and Zoe. While Kartik plays Raghu and Veer, Sara Ali Khan has been cast as Zoe and Arushi Sharma plays Leena.
