"a critical and box-office cottage industry" dịch là gì hả các bác?

Câu hỏi như trên

Ko có context thì dịch thế qué nào
Còn cái "cottage industry" = a small business run from home (ref: CALD 3rd e***ion)

Oh đây là context: "Bill Newcott, entertainment e***or of the magazine, says: "In 2009, 50+ actors and filmmakers took center-stage on the silver screen, turning in performances and films that were riveting and nothing short of daring. Tackling war, apartheid, ***uality and adding real depth to romantic comedies, the 50+ Hollywood community shows once again that they are an integral, much-needed element of the film industry. And 60-year old Meryl Streep proved without a doubt that she is the leading lady of our times, a critical and box-office cottage industry." . Mình cần dịch đoạn in đậm.
Many thanks!
