Can we draw the following hypothesis from the context?

Context:

The Real Howard Spitz is a 1998 family comedy film directed by Vadim Jean, produced by Paul Brooks and written by Jurgen Wolff. Starring Kelsey Grammer, Amanda Donohoe and Genevieve Tessier, it is a Canadian and U.K co-production. A failed detective writer, Howard Spitz has hit rock bottom until an 8-year-old girl helps him write children's books.

Hypothesis: Kelsey Grammer and Amanda Donohoe are Canadian.
It's impossible to say
