The Odd Couple HKL trailer says Lau-Kar Leung?

[Omni Dragon]

I just watchted the HKL trailer of Odd Couple & right at the start it says "From action superstar Sammo Hung and Shaw Brothers Legend Lau Kar-Leung" this must be a mix up because his brother Lau Kar-wing is in it & a small possibility because Leung is also so in Leung Kar-yan's name who is also in the film. Personally i think it's possible because as Bey said "Medusa, was bought out by another one, Contender, who didn't understand the Asian market as well." so it could be possibly or maybe the person who did the writing didn't know much about the films. Does anyone else know of any possibilities or more information into it?
