A spokesperson for troubled Friends
actor Matthew Perry
denies a report that production was halted on his latest film, Servicing Sara
, as a result of his entering rehab. "I think they've got several days of scenes to do without Matthew, so they are in production," Lisa Kasteler
. Meanwhile, in a conference call with reporters, NBC Entertainment President Jeff Zucker
producers "don't expect [Perry's absence] to have a big impact, but it's still early and we can't say beyond that."
