The Hong Kong Film Archive released
The Secret restoration on Blu in 2019, and it was also in Carlotta's Hui box from earlier this year. The HKFA disc (which has English subs) is available from a few international sources (including eBay), though at a hefty markup. The HKFA also released the
Colorful Youth restoration, including an extended version with additional footage sourced from a VHS tape, but on DVD only.
The restorations of
The Arch and
Just Like Weather are part of the
M+ Restoration initiative, which has also restored Peter Yung's
The System and Patrick Tam's
Love Massacre. The series will eventually include
The Butterfly Murders (Tsui),
The Story of Woo Viet (Hui),
Homecoming (Yim),
Cageman (Cheung), and
Durian Durian (Chan). AFAIK none of these restorations have been commercially released yet, but Kani will be putting out
Cageman and
Just Like Weather in the U.S. Les Blank (who was the film's editor) acquired the U.S. rights to
The Arch at some point and his company still
sells it on their site, but in a dreadful old transfer.
