They say the more the better. Will more lead actors in one movie be better too? Movies with many top actors in one place are preparing to meet fans continuously.
"Sector 7"- Ha Ji-won, Oh Ji-oh and Ahn Seong-gi
She's back as a female warrior from being stuntwoman Gil Ra-im in "Secret Garden". Actress Ha Ji-won has finished filming the 3D blockbuster movie "Sector 7" (director Kim Ji-hoon, produced by JK Films) and is about to be released.
"Sector 7" is about the crew on an oil prospecting ship fighting with an unknown creature. Besides, Ha Ji-won there is a massive cast made up of Ahn Seong-gi, Oh Ji-ho, Song Sae-byeok, Park Cheol-min, Cha Ye-ryeon and others. A spokesperson for "Sector 7" says, "The actors' roles, a supportive scenario, fancy attractions will make this work. It will be the hit of the summer".

"Tower"- Seol Kyeong-gu, Son Ye-jin and Kim Sang-kyeong
Box office hit ticket Seol Kyeong-gu selected the movie "Tower" (Director Kim Ji-hoon, produced by CJ E&M movies, and The Tower Pictures) as his next big thing. Son Ye-jin and Kim Sang-kyeong have also come on board.
"Tower" is a blockbuster about a fire happening in a high-rise building in the middle of the city and the people that fight to survive from it. Director Kim Ji-hoon from "Sector 7" has the megaphone.
Seol Kyeong-gu is fireman Kang Young-gi who dives into the fire to save another soul. Son Ye-jin is Seo Yoon-hee, the restaurant manager of the building that is on fire. Kim Sang-kyeong is Lee Dae-ho, the facility manager.

"The Professionals – Kim Yoon-seok, Kim Hye-soo and Jeon Ji-hyeon
Known as the Korean "Ocean's Eleven", "The Professionals" (director Choi Dong-hoon and produced by Caper Films) was an issue from the start for being the Choi Dong-hoon team and new faces. Choi Dong-hoon's previous works, "War of the Flowers" and "Jeonwoochi" cast Kim Yoon-seok, Kim Hye-soo and Jeon Ji-hyeon have joined the team. Also, Kim Soo-hyeon-I who rose to stardom from KBS 2TV "Dream High" has confirmed cast, establishing a firm base of organization.
"The Professionals" draws the episodes of thieves that try to steal a diamond worth 40 billion won, hidden in a casino in Macao. It is also in question if director Choi Dong-hoon can carry on his relay of hits starting from "The Big Swindle". "The Professionals" cranks in in May.
