Across the sea review
12 May 2010 | by (Norway) – See all my reviews

Starting with this beautiful woman in the water, but on from that.. Some green stuff on the beach, might be interesting:) Allison Janney, i love her, but i think a "unknown" would be better here. (error 1) Allison tells species of plant she is crushing, poles. Babies! "I only picked one name." Stupidest line in the series. (error 2) Kids who look like they belong in High School Musical... (syntax error) Mark Pellegrino is always interesting in my eyes, especially in Mulholland Dr. and most memorable from Lebowski. But this might be superseding it, just have to wait.. Anyway, eggs are eggs right, so two more weeks and we have the answer to what eggs really are.
