Screen Actors Guild (SAG) screening of Death at a Funeral

A stateside friend of Flip's went to the SAG screening of DAAF, where there was a Q&A with Frank Oz.  The following was said about Keeley Hawes and Matthew Macfadyen

had an email from a friend in the states who attended the SAG screening and Q+A with the director the other evening, thought this bit was quite cute:
"Oz said that she [Keeley] was pregnant during the filming and mentioned a scene where Matthew moved his legs over on the couch so as to cover up the fact that she was pregnant so it wouldn't be seen on film (since she's not pregnant in the plot)..."
