NBC has put in development Better Late Than Never, a reality series based on the South Korean format Grandpas Over Flowers from content company CJ E&M. Craig Zadan and Neil Meron (The Sound Of Music, Smash) will produce the project, which draws parallels to Betty White’s Off Their Rockers that started on NBC. In Better Late Than Ever, four veteran actors go backpacking across Asian countries with a young guy who does chores for them along the way. The original series, which aired for two seasons on channel tvN, featured a group of 70- and 80-something guys backpacking though Europe. Watch the English-language trailer above.

South Korea is emerging as a hot format source this season. CBS is developing a medical drama based on the South Korean series Good Doctor.
