SBS recently revealed still cuts from the filming of its new drama, 'Phantom', which will air on Wednesdays and Thursdays with the conclusion of 'Rooftop Prince'.

The filming took place in early May with main leads So Ji Sub and�Lee Yeon Hee, as well as other cast members.

Filmed on a cloudless day at a helicopter landing pad on top of a large building, So Ji Sub, Lee Yeon Hee, and Kwak Do Won showed a passion for their work despite the heat.

So Ji Sub wore a simple stylish suit,�while Lee Yeon Hee dazzled with her men-inspired outfit complete with a loosely draped tie and blazer.

One drama representative praised Lee Yeon Hee stating, "She has the beauty of a 'sun goddess'".

'Phantom' will tell of the story of cyber investigators So Ji Sub and Lee Yeon Hee, and will start airing later this month.
