The much-anticipated return of tvN's hit drama Signal generates excitement as reports of on-set sightings surface.

On March 5, an online community post featured images of actors Cho Jin Woong and Lee Jae Hoon actively filming for 'Signal 2.'

In the released photos, Lee Je Hoon is seen playfully making a V-sign, exuding charm, while Cho Jin Woong appears with a noticeably larger belly, sparking discussions among fans. Some speculate that he gained weight for the role, while others believe it could be part of his character's makeup. 

Meanwhile, actress Kim Hye Soo drew attention by posting a behind-the-scenes photo on her Instagram story without any caption. The image included a sign reading "Private Dressing Room - 3, Second Signal, Cha Soo Hyun, Kim Hye Soo," further heightening fans’ anticipation.

First aired in 2016, Signal captivated audiences with its unique crime-thriller narrative. In it, detectives from the past and present, connected through a mysterious walkie-talkie, work together to solve long-unsolved cases. The series gained immense popularity, leading to remakes in Japan (2020) and Thailand (2022).

The sequel, 'Signal 2: The Second Signal,' is set to premiere in the first half of next year. With the original cast members Kim Hye Soo, Cho Jin Woong, and Lee Je Hoon reprising their roles, expectations among fans are soaring.
