Rings a bell.
If it had a comedy-aspect it might be "Love at First Bite". Can't recall the end right now, but the three bites are definitely true for this one.
Could be it. Thanks![/quote]
Another title that come to mind is
Once Bitten, which has Jim Carrey in it. I haven't seen it myself, so I cannot comment on the plot.
I believe the theme of several bites being needed for transformation was at least used in
Horror of Dracula, the original Christopher Lee film. Isn't it also used in
Bram Stoker's Dracula by Coppola? I believe we also see Mina's friend hiding the bitemarks at first, while still being able to roam in daylight.
