The producer of the movie Paul Walker was shooting when he died says production is on hold right now ... telling TMZ there are more important things to worry about.

Neal Moritz -- who's produced all the "Fast & Furious" movies -- is currently shooting "F&F7"  and, as TMZ reported, the film was scheduled to resume shooting key scenes with Walker this week in Atlanta. 

Moritz was somber and struggled for words when we saw him last night at LAX ...  he told us the cast and crew need time to mourn Walker's death ... before they can decide how to proceed with the movie.
