Iron Road 

In 1882 British Columbia, Alfred Nichol (Sam Neill) is desperate to get Chinese labor as he falls behind crossing the Rocky Mountains. He sends his son James to Hong Kong to gather 2000 workers in one week before Chinese New Year. Their sickly drunken contact Lionel Relic (Peter O'Toole) is having trouble. Little Tiger is an orphan girl passing as a boy. She sells fireworks and learns explosives from the master. She befriends Lionel but James refuses to take her. They battle gangster Lei Mo over workers. Tiger recruits the last 100. Lionel is killed and James takes her fearing for her life. She starts out as the tea boy and volunteers to crawl in after a cave-in to set explosive charges. She starts falling for James despite her secret identity and his girlfriend Melanie Grant (Charlotte Sullivan).

This is a functional love story weaving in the historical drama. Sun Li and Luke Macfarlan are surprisingly good despite being relative unknowns. She's able to shine and he's able to stay in the picture despite having to compete against some A level talents. O'Toole is in the first part. He's a frail man but he still brings it. Both the English and Chinese actors are very professional. The production value is limited. At least, they have a real train and a tunnel. The Hong Kong set looks very fake. They probably built it in Canada which explains it. It's a solid TV mini-series.
