My suggestions for cast . Looked at age appropriate talent.
Rick Hunter – Tom Holland. Young, goofy, naïve, yet can get serious
Lisa Hayes – Alicia Vikander. Older than Tom Holland, but can still see as a love interest. Tomb Raider showed she can be tough character too.
Lynn Minmei- Rose (from Blackpink). Speaks perfect English with Australian accent and already fits the role as a Kpop singer. The Minmei character is Chinese, so must be Asian actress to avoid white washing controversies.
Max Sterling – Timothee Chalamet – Rising young actor. Has slightly nerdy look but can be very sexy too.
Miriya Parina - Mila Kunis or Eiza Gonzalez – Got the sharp look that can be softened by love.
Roy Fokker – Matthew McConaughey - tall, built, humorous. McConaughey might be too old but his image fits the character very well.
Claudia Grant – Nathalie Emmanuel - tall, beautiful, older
Henry Gloval - Liam Neeson - tall, broad shoulders, has the protective but assertive father figure thing going on.
Ben Dixon – Jonah Hill – comic relief and can be serious too.
Lynn Kyle – Ludi Lin – From Power Rangers. Has the Asian actor look and can look smug.
Khyron - Tom Hiddleston
Azonia - Carla Gugino - older, beautiful, can definitely pull off a mature and slightly evil role
Breetai – Joel Kinnaman – Tall, built. Has played bad guy roles and good guy roles.
Exedore - Danny Pudi
Dolza – Dean Norris (Breaking Bad)
I think this looks good!
