ViuTV show, Actor • Door (演員.門) invited Louis Cheung (張繼聰) and Ivana Wong (王菀之) as guests. He also revealed there was a special reason behind Nick Cheung (張家輝) approaching him to film Keeper of Darkness (陀地驅魔人) movie at the time.

When Ivana and Louis disclosed about using different methods to gain attention, Louis said: “When Nick invited me to shoot Keeper of Darkness film, I asked him if he watched my work and he said nope. Hence, I questioned him about the reason for approaching me.” It turned out that Louis had designed a plan for himself and wore blue top for a year, and Nick happened to read the news article. He continued: “Nick said he appreciated me and decided to look for me to play the role.” It is indeed an interesting process.

Although Louis and Ivana participated in comedy films most of the time, but Louis did shoot Madalena (馬達.蓮娜) movie together with Chrissie Chau (周秀娜) while Ivana agreed to film Our Time Will Come (明月幾時有) directed by Ann Hui (許鞍華). She said shyly: “I shoot drama as well but everyone laughs upon seeing me. I am an actress.” The hosts then laughed loudly.
