  In the collapsar model for common gamma-ray bursts, the formation of a
centrifugally supported disk occurs during the first $\sim$10 seconds following
the collapse of the iron core in a massive star. This only occurs in a small
fraction of massive stellar deaths, however, and requires unusual conditions. A
much more frequent occurrence could be the death of a star that makes a black
hole and a weak or absent outgoing shock, but in a progenitor that only has
enough angular momentum in its outermost layers to make a disk. We consider
several cases where this is likely to occur - blue supergiants with low mass
loss rates, tidally-interacting binaries involving either helium stars or giant
stars, and the collapse to a black hole of very massive pair-instability
supernovae. These events have in common the accretion of a solar mass or so of
material through a disk over a period much longer than the duration of a common
gamma-ray burst. A broad range of powers is possible, $10^{47}$ to
$10^{50}\,$erg s$^{-1}$, and this brightness could be enhanced by beaming. Such
events were probably more frequent in the early universe where mass loss rates
were lower. Indeed this could be one of the most common forms of gamma-ray
transients in the universe and could be used to study first generation stars.
Several events could be active in the sky at any one time. A recent example of
this sort of event may have been the SWIFT transient Sw-1644+57.
