A recent community forum post had netizens talking about the most successful motion picture starring idol-turned actors. 

On May 12th, a post asking for the most successful motion picture starring idol-turned actors gained attention on a popular online forum. As there would be numerous answers to this question, the original poster limited the answers to idol-turned actors who are no longer promoted as an idol. 

According to the comments under this post, films and dramas such as 'Architecture 101' (starring Suzy), 'The Penthouse'(starring Eugene), 'The Attorney'(starring Siwan), 'Incomplete Life'(also starring Siwan), 'Kill Me Heal Me'(starring Hwang Jung Eum), and 'Coffee Prince' (starring Yoon Eun Hye) were mentioned as the most successful motion picture starring idol-turned actors. 

But many comments pointed out there are so many more successful series and films even if the original poster limited the answers to idol-turned actors who are no longer an idol. 

What else comes to your mind?
