Problem subclassing tuple

Given this class:
class Holder(tuple):
def __init__(self, *values):
tuple.__init__(self, values)
When I try to create an instance:
Holder(1, 2)
I get:
TypeError: tuple() takes at most 1 argument (2 given)
It looks like the constructor for the superclass is being called rather than
the __init__ method on Holder.
I'm obviously missing something here. Do I have to supply a __new__ method?
Any help would be appreciated.
