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 told Reuters. Meanwhile, in a conference call with reporters, NBC Entertainment President Jeff Zucker said Friends producers "don't expect [Perry's absence] to have a big impact, but it's still early and we can't say beyond that."
